Sun Java System Web Server 7.0 Update 7 Performance Tuning, Sizing, and Scaling Guide

Accelerator Hit Ratio

The number of times the response for a request that can be accelerated was found in the accelerator cache. Web Server can also serve requests from the accelerator cache asynchronously directly from the keep-alive threads thereby bypassing the connection queue altogether. This leads to improved performance for these requests and at the same time reduces contention on the connection queue.

Tuning

Higher hit ratios result in better performance. To maximize the hit ratio, see the tuning information for Acceleratable Responses.
