Change the default value of ssl_session_cache?

[huanghc]

The Nginx official document recommends to enable ssl_session_cache and set that to shared:name:size, which enables cache shared between all worker processes.

"To reduce the processor load it is recommended to set the number of worker processes equal to the number of processors, enable keep-alive connections,enable the shared session cache,"

I wonder whether the default setting need to be changed. Thanks.
