Performance under Heavy Disk Access RRS feed

  • Question

  • I have windows 7 on an SSD but this is a problem with every hard drive on every PC I've ever had.

    Under high disk read/write, once the disk I/O saturates and it's at 100% active time, Windows freezes intermittently. It seems like when SVCHOST or a similar process has a long queue time (~seconds), Windows freezes and generally can't do anything. I have 24GB of memory and no paging file.

    Is there a way to make Windows load more stuff into memory so it isn't reliant on disk access? Is there a way to prioritize the system so that certain things (like svchost, explorer) interrupt the queue and the system doesn't have to hang while waiting?

  • When Windows detects a SSD the Superfetch service is disabled which prefetches data to the RAM. You can try to start the service your own.

  • Superfetch has been running, not sure if it does anything

  • Download RAMMap [1] and run it. Look at the standby list. How much is used?
