FMW 11g Web Cache performs poorly. There are frequent periods of latency when requesting any files via Web Cache.
Monitoring the Web Cache access_log file while cycling requests (using wget from the command line) to a small 2k image file confirms frequent delays:
The above snippet from the Web Cache access log file gives a breakdown of where the time is being spent and the delay is mainly in r-time-taken (the second from last column), the time between the 1st byte of the request sent to the Origin Server and the last byte received. The columns are time-taken, c-ip, date, time, cs-method, cs-uri, bytes, x-time-reqrecvlatency, x-time-respsendlatency, x-time-delay, r-time-taken, x-time-end.
Nothing unusual is seen in the event_log.
This unrelated to the Throttling setting which is set to NO, in webcache.xml, with the statement <TWEAKPARAM NAME="OSTHROTTLING" VALUE="NO"/>
Requests direct to the HTTP Server (OHS) shows a consistent response time.
