- Disk Thrashing
- On a system with Virtual Memory, pages of memory are read from and
written to the swap file as necessary. Disk Thrashing is when there is
excessive paging, specifically when the I/O system is busy paging memory
but the CPU is not fully utilized - generally if the system is
unresponsive (i.e. slow) and there is lots of disk activity then the
system is likely to be thrashing.
If disk thrashing is a problem then a short term solution may be to reduce the number of running applications. A longer term solution is to add more memory.
Also known as Thrashing.
