The less data a disk has on it, the faster it will operate. This is because on a well defragmented drive, data is written as close to the outer edge of the disk as possible, as this is where the disk spins the fastest and yields the best performance. Disk seek time is normally considerably longer than read or write activities.
As noted above, data is initially written to the outside edge of a disk. As demand for disk storage increases and free space reduces, data is written closer to the center of the disk. This means that monitoring disk space utilization is important not just for capacity reasons but for performance also. Run a defragmenter utility regularly on your disks, including the root drive, to prevent performance degradation.
Do this weekly on busy disks. A disk defragmenter is installed with Windows and can be run from a Scheduled Task at specified intervals. Windows Server uses preemptive multi-tasking to prioritize process threads that will be attended to by the CPU.
Preemptive multi-tasking is a methodology whereby the execution of a process is halted and another process is started, at the discretion of the operating system. This scheme prevents a single thread from dominating the CPU. Switching the CPU from executing one process to the next is known as context-switching. The Windows operating system includes a setting that determines how long individual threads are allowed to run on the CPU before a context-switch occurs and the next thread is serviced.
This amount of time is referred to as a quantum. This setting lets you choose how processor quanta are shared between foreground programs and background services. Typically for a server it is not desirable to allow a foreground program to have more CPU time allocated to it than background services. That is, all applications and their processes running on the server should be given equal consideration for CPU time.
To increase performance for background service like BizTalk host instances, follow these steps:. Click Start , click Control Panel , and then click System.
Click the Advanced tab, and then click Settings under Performance. Click the Advanced tab, click Background services , and then click OK twice. A default installation of Windows Server enables several services that may not be required in a BizTalk Server environment. Each running service consumes system resources and so unnecessary services should be disabled to improve overall performance.
Care should be taken when disabling services. Thoroughly research the purpose of a service before disabling the service as Windows Server requires certain services are running. If services required by Windows Server are disabled, the operating system may become inoperable and possibly even unable to boot. To disable Windows Server services that are not required for a dedicated BizTalk Server, follow these steps:. In the Status column, each service that is running is labeled "Started.
Note the services that depend on each service that you want to disable. To do this, follow these steps:. In the This service depends on the following system components list, note the services this service depends on. In the The following system components depend on this service list, note the services that cannot start without this service, and then click OK. If the Stop Other Services dialog box appears, note the other dependent services that will also stop, and then click Yes , and then click OK.
Test the server for correct operation after you disable each service to make sure you did not disable a service you want to continue to use. When starting a. NET application, the. If your system does not have direct access to the Internet, or is restricted from accessing the Microsoft. To avoid this delay at application startup, you can use the following steps to manually download and install the code signing Certificate Revocation Lists on your system.
From a command prompt, enter the following command to use the certutil utility to update the local certificate store with the CRL downloaded in step Mapped files bypass the system disk caches, so only one copy of the file is stored in memory. For more information about mapping files into memory, see Mapping Files Into Memory.
For security reasons, file systems are supposed to zero out areas on disk when they are allocated to a file. This behavior prevents data leftover from a previously deleted file from being included with the new file. However, in OS X version For both reading and writing operations, the system delays the writing of zeroes until the last possible moment. When you close a file after writing to it, the system writes zeroes to any portions of the file your code did not touch.
When reading from a file, the system writes zeroes to new areas only when your code attempts to read from that area or when it closes the file. If you notice a delay when closing your files, it is likely because of this zero-fill behavior. Make sure you do the following when working with files:. Write data to files sequentially. Gaps in writing must be filled with zeros when the file is saved.
Truncate files to match the length of the data you wrote. For scratch files you plan to delete, truncate the file to zero-length. Converting pathname information from one form to another is often an expensive operation.
The best time to cache is when you know you are going to need that same structure again. Reusing file-related data structures minimizes the interactions your program has with the file system. OS X version Now, changes to the kernel allow those same operations to be performed in parallel. When reading data from the disk to a local buffer, the buffer size you choose can have a dramatic effect on the speed of the operation.
If you are working with relatively large files, it does not make sense to allocate a 1K buffer to read and process the data in small chunks. Instead, it is advisable to create a larger buffer say K to K in size and read much or all of the data into memory before processing it. The same rules apply for writing data to the disk: write data as sequentially as you can using a single file-system call. If you have photos, music, or other files that you want to keep but don't use often, consider saving them to removable media, like a USB drive.
You'll still be able to use them when the drive is connected, but they won't take up space on your PC. Select File Explorer from the taskbar and find the files you want to move. Select your removable media from the location list, then select Move. Get more info about freeing drive space in Windows. Windows 11 includes many visual effects, such as animations and shadow effects. These look great, but they can also use additional system resources and can slow down your PC.
Select Search , type performance , then select Adjust the appearance and performance of Windows in the list of results. Your PC settings let you choose where files will be saved by default.
You can save files on your PC or to OneDrive by default and sync files between the two locations. This lets you get to your files from any device that can connect to the internet, and it helps make sure your files are backed up in case your PC is ever damaged or lost.
You can pause OneDrive syncing temporarily and see if it helps improve your PC performance. You can also visit Fix OneDrive sync problems to check for any sync issues. When you turn on your PC, some programs start automatically and run in the background. Many programs are designed to start automatically when Windows does.
Sometimes you can determine which programs start automatically by looking at the program icons in the notification area on the far right of the taskbar. To try to find out the name of the program, point to the icon with your mouse pointer.
Even after you check the notification area, you might still miss some programs that run automatically at startup. To stop a program from starting automatically. Open Startup Apps settings. In the Startup Apps area, find the program you want to stop from starting automatically and set it to Off. Note: If you turn off a program and it continues to start automatically when Windows starts, you should scan for viruses and malware. See the next section for more info. A virus, malware, or malicious software could cause your PC to run slowly.
Other symptoms include unexpected pop-up messages, programs that unexpectedly start automatically, or the sound of your hard disk constantly working. The best way to handle viruses and malicious software is to try to prevent them by running antimalware and antivirus software and keeping it up to date. However, even if you take precautions, your PC can still become infected.
For more info, see How to protect your Windows PC. If they are, choose the one you want to run, and then disable or uninstall any others. If you have another antivirus program installed and turned on, Windows Security will be turned off by default. To scan for viruses using Windows Security. Open Windows Security settings. On the Protection updates screen, select Check for updates to make sure you have the most recent updates. Wait for Windows Security to finish scanning for viruses and malware.
Run the recommended advanced scan. This scan takes longer but searches more extensively for threats on your PC. If no viruses are found, restart your PC and try to reproduce the performance problem you were having with your PC. To scan for malware and viruses with Microsoft Defender Offline. The scan might take 15 minutes or so, and your PC will restart again after that. Restoring your PC undoes recent changes that might be causing problems.
If you think a recently installed app, driver, or update for Windows could be causing problems, you might get things running normally again by restoring your PC to an earlier point, called a restore point. Select Search on the taskbar, type advanced system , then select View advanced system settings from the list of results.
On the System Protection tab, select System Restore. Select Recommended restore to go with the most recent restore point Windows has made automatically, or Choose a different restore point to select one yourself, then select Next.
If you chose to select a different restore point, select one, then select Next. Either way, select Finish to begin restoring. In the search box on the taskbar, type create a restore point , then select Create a restore point from the list of results. On the System Protection tab, select Configure.
One of the best ways to get the most out of your PC is to make sure you have the latest version of Windows 10 installed. Sometimes apps that were made for an earlier version of Windows will still run on Windows 10, but they might slow down your PC. In the search box on the taskbar, type troubleshoot , then select Troubleshoot settings , which has System settings listed underneath it.
Select File Explorer from the taskbar. In the search box on the taskbar, type advanced system , and then select View advanced system settings , which has Control panel listed underneath it.
In the Temporary Files area, select Delete temporary files that my apps aren't using. Select which files you want Storage Sense to delete your choices are files in your Recycle Bin and in your Downloads folder , then select the corresponding time intervals. Windows will take a few moment to clean up your files, and then you'll see a message indicating how much disk space has been freed up.
In the search box on the taskbar, type disk cleanup , then select Disk Cleanup from the list of results.
