FMW 11g Web Cache Response Time Performance Slow For All Requests
(Doc ID 1358825.1)
Last updated on FEBRUARY 01, 2024
Applies to:
Web Cache - Version 11.1.1.3.0 to 11.1.1.5.0 [Release Oracle11g]Information in this document applies to any platform.
Symptoms
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.
