Is it better or not to have SysMain?


Win will try avoid using this method when there is RAM available, but when some data requires a large amount of memory while RAM is not full.

The system will compress data (compress) by placing them in the RAM for save resources and try to force the best work out of the computer.

Most of data is stored in RAM so that the system can access it directly and without problem.

In virtual memory, or as we also call the paging file, the data is stored on the hard drive, which reduces the time it takes to convert data from hard drive to RAM.

Some users find that Memory is sometimes crowded up to 3.5 GB, but it’s not that bad when you have 100% hard drive can be paging file. Just wait until the data is compressed in the RAM.

If anyone wants enable or disable the “SysMain service host”, then you find it in the task manager.

The conclusion is simple and it is obvious that compressed memory is much better than paging file, which is even on an SSD drive.

I do not recommend deactivate this service.
