IS IT GOOD OR BAD TO HAVE SYSMAIN?
Windows will try to avoid using this method when there is available RAM, but when some data requires a large amount of memory when RAM is not tight, the system will compress the data (compress) by putting it into RAM to save resources and try to force computer work best.
Most of the data is stored in RAM so that the system can access them directly and without problems. In the virtual memory, or as the paging file is also called, the data is stored on the hard disk, thereby reducing the time for converting the data from the hard disk to the RAM. Some users see that the memory is sometimes clogged up to 3.5 GB, but it’s not so bad when you have a hard disk at 100 percent may be from the paging file. You just need to wait until the data is compressed into RAM.
If someone wants to Enable or Disable “Host service: SysMain”, then find the SysMain service in Device Manager. The conclusion is one and it is obvious that the compressed memory is much better than the paging file, which is even on an SSD disk.
I do not recommend disabling this service.
