Monitors the Current Cache Fetches Avg Ms Per Request on ISA Server 2006 Cache.
This monitor checks the average time to fetch a URL from cache.
Expect 1–50 milliseconds. Suspect if more than 300.
May indicates that disk transfers are higher than capacity. For more information, see \PhysicalDisk(*)\Disk Transfers/sec.
Disk I/O rate. Correlates with disk seek rate, and depends on Web cache hit ratio.
A 10,000 RPM disk can do 100 maximum, and a 15,000 RPM disk can do 150 maximum.
If a disk is used only for ISA Server Web caching, and this counter is greater than the maximum, expect slow responses from ISA Server Web Proxy.
If no other process is using this disk, add another physical disk and define a Web cache file on it.
