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.
