If you\u2019ve made the jump and updated to Windows 10<\/a>, you might have noticed something strange: the System process sometimes takes up an insane amount of RAM, possibly over 1GB. That\u2019s actually not a bug, it\u2019s a feature of Windows 10. Here\u2019s how it works.<\/p>\n Before we explain what\u2019s going on in the new versions of Windows, let\u2019s talk about how previous versions of Windows have handled memory usage. You only have so much space in RAM to store data. If you fill up your computer\u2019s memory, Windows would offload the least used pages of data to the pagefile<\/a>, which resides on your hard drive.<\/p>\n The downside to this method is that if you need to use data from your pagefile again, it has to get it from the much slower hard drive, rather than loading it from ultra-fast memory. While that\u2019s better than an app crashing, it would still be better if that data didn\u2019t have to leave memory at all.<\/p>\n Windows 10 still uses a pagefile when it has to. However, now when your computer\u2019s memory starts to fill up, Windows 10 will start compressing<\/em> old pages of memory so they take up less space, similar to what happens when you create a ZIP archive of multiple files. So, for example, if you have an app running that you haven\u2019t touched in a while, rather than copying the information about that app to your hard drive, Windows will simply make it smaller, but keep it in memory.<\/p>\n The trade off, of course, is that decompressing the compressed memory takes up more CPU cycles. Typically, however, this performance cost is much, much lower<\/a> than it would be if the system had to retrieve data from a hard drive (even SSDs). So even with the compression, it\u2019s faster to pull those old apps out of memory than it is to load them from the hard drive\u2019s pagefile.<\/p>\n All of the compressed memory that Windows 10 creates is stored in the System process. This is why it appears to balloon over time. The longer you have your computer running (and the more applications or browser tabs you launch), the more data in memory Windows will need to compress.<\/p>\n Mac users have been using a very similar feature since 2013<\/a>, and even newer versions of the Linux kernel employ a type of memory compression<\/a>. Despite the fact that it looks worrying in the Task Manager, this method of conserving memory is not only better, but already pretty common among other operating systems.<\/p>\n For starters, you don\u2019t necessarily need<\/em> to do anything about this. As we\u2019ve discussed before, unused RAM is wasted RAM<\/a>. Closing applications to \u201csave RAM\u201d just means it\u2019s going to take longer to load them when you need them again. Unless your computer is running slowly, you shouldn\u2019t worry about programs using lots of RAM. It\u2019s a good thing.<\/p>\n However, as we stated before, decompressing that compressed memory now uses more CPU cycles rather than just loading from the hard drive, so it\u2019s possible to see a brief performance hit when switching to an application you haven\u2019t touched in a while. If this is happening to you, there are a few things you can do. But they\u2019re pretty much the same solutions you\u2019ve always had:<\/p>\n Ultimately, not much has really changed. The way you handle high memory usage isn\u2019t substantially different than it was in previous versions of Windows\u2014it\u2019s just a little off-putting when you first see it in the task manager. But don\u2019t worry: the System process is just working even harder to make sure your computer runs as smoothly as possible.<\/p>\n<\/p>\n via https:\/\/ift.tt\/1LjrXtw<\/p>\n","protected":false},"excerpt":{"rendered":" If you\u2019ve made the jump and updated to Windows 10, you might have noticed something strange: the System process sometimes takes up an insane amount of RAM, possibly over 1GB.
