Design Decision: Performance Considerations
Should I enable Machine Creation Services I/O (MCSIO) cache?
If Service Level Agreements (SLAs) are not required in your environment, use the less expensive standard disk for the MCSIO cache
Consider enabling MCSIO cache when user experience is a high priority. The fast response times of the memory cache make a noticeable difference for the users.
Using a memory cache size of 2 GiB provides the best improvement without negatively impacting user density. Always account for the extra memory when choosing an instance size for the workload
Do not enable MCSIO cache on memory-constrained machines, such as the F/FS series where the memory to CPU ratios are low
