It seems that Windows creates an internal hash table of all paged out pages could be also a B-tree and adds them to the MemCompression process only if the newly compressed pages was not already encountered. In sum, we expect users to experience improved overall responsiveness and usability on all devices running Windows 10. If you would like to learn more about compressed memory in Windows 10, check out this great video on. One of the primary goals of any operating system is to manage and share resources efficiently. Is it a good idea to commit all of your physical memory? I have made some experiments on my machine and others.
The end result is a snappier, more responsive experience with improved app launch performance and consistency. But for some server workloads it made sense to use larger pages. The default setting for this threshold is an 8:1 compression ratio. Don't worry, you are not witnessing a memory leak in progress, it is memory compression at work. In Windows 10, this works by moving pages from the stores in the system process to the modified list. Figure D You can see how much memory is compressed in Task manager.
Note that if the memory still has pressure then pages from the compression store user mode System process space can be placed on the modified list they are now compressed which can then be written to the physical pagefile the system will see they are from the system user mode space and compressed and therefore won't try to put them back in the store. A special case are page file allocated memory mapped files. The upshot of this is that most data will be kept in memory reducing pagefile use but you will see System using lots more memory since this is essentially the in-memory, compressed pagefile content. The interesting question is: Is this a good idea? In some situations, such as in , auxiliary storage is limited or non-existent. Every number you will ever see with regards to memory consumption is wrong or a lie to some extent.
Thanks, Ethan Creeger — Program Manager in the Base Platform team. An easier metric is to sum up all committed memory which is by definition local to your process. I don't think you should turn it off as I don't know what the repercussions of it might be. In a more recent version of Windows 10, Microsoft again refined the name of the process to Memory Compression, but also hid it such that it no longer shows up in Task Manager's Processes list. A private working set represents physical memory that is unique to a process. First, observe the amount of memory used by the System process: Then, start and suspend some applications:.
But like I said, with a little playing around I got it working to the point where I can follow what you are saying, thanks. In general it is nearly never a good idea to trim your own working set. They can say what they want, but compressing 4gb takes a chunk of power, yet if my use rarely exceeds phsyical available memory, then it can be completely avoided. First, press the Windows key + X. Note this is very rare on all but the most memory constrained systems. However, since modern systems have multiple cores, the operating system can delegate this task to other cores that might otherwise be idle. However, for those without any other option, you may need to disable the service.
First page touch: 366ms, 0. From what I read on google, I would have to disabled the super fetch service. Something else must be happening here. The compression feature also will not touch anything that is accessed frequently, as a game would do. On , we can confirm that compressed memory is only displayed under Memory details, and the System process stays at 0.
Still, good to point it out. Not only is the process fast, but the space-saving aspect of the compression is considerable. Please get back to us with the results to assist you further. To answer that question one needs to understand how memory management works in detail. What do you think about the memory compression feature in Windows 10? I decided to do a refresh and everything was fine, so I guess drivers can get messed up in an update.
Do i subtract that 568+340mb from real in use phsyical memory? Without memory compression, our system would have 6. From a developers points of view memory is only a new xxxx away. Unsourced material may be challenged and removed. Have you found a solution to your problem yet? This is visible in the task manager. Process Explorer and Process Hacker have no column named Committed memory. So placebo effect or not, I do not need the compression, makes more sense when memory starved.
