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

Maximum Threads and Queue Size

When configuring Web Server to be used with SNCA, disabling the thread pool provides better performance. These settings are on the configuration's Performance tab ⇒ HTTP sub tab, under Thread Pool Settings. To disable the thread pool, deselect the Thread Pool Enabled checkbox. You can also disable the thread pool using the wadm set-thread-pool-prop command's enabled property.

The thread pool can also be disabled with non-SNCA configurations, especially for cases in which short latency responses with no keep-alives must be delivered.
