The System process high memory usage in Windows 10

Процесс System и высокое потребление памяти в Windows 10

Many users of the newly minted Windows 10, showing concern that in some cases the operating system consumes too much memory. In particular, we are talking about the process System, the needs of which the operating system can allocate even a few gigabytes.

Why is this happening and can anything be done to resolve this? In fact there is no need to do anything. We just need to understand why the high RAM consumption by this particular process is not bad, but on the contrary, is a «symptom» of one of the improvements that incorporates Windows 10.

It’s not a bug, it’s a feature

This may seem like a joke, but the fact that the process System in Windows 10 can consume 4 GB of RAM (or more) is not a memory leak or another serious problem, and improving the memory management mechanism that improves the performance of applications.

In Windows 8 and earlier versions, when no free memory, the system automatically moves the data of running applications in the paging file, which is located on the hard disk serves as virtual memory. However, because the speed of reading data from a hard drive far, far below that of RAM, this leads to a marked decrease of responsiveness of the applications whose data are available in the paging file.

Of course, the swap file is in Windows 10, but before using it, the system strives to implement the best solution, namely, to compress unused data to keep in memory as many applications. In this case, the output is lower than normal storage of data in RAM (because re-use requires compressed data decompression), but higher than when accessing the applications that reside on the disk (the paging file).

Compression operates within the System and that is why this process sometimes can «consume» a few gigabytes.
