NOTES on "strange pause" during testing run
Test conditions:
Client Configuration:
- JMeter 2.4 being run on a Windows XP box
- Testing 4 HTML (over HTTPS) pages
- Key Issue - when "Retrieve All Embedded Resources" is enabled, test runs for ~500-600 iterations (2400 of the 4 pages + 10X that in embedded resources), then pauses for about 35 seconds, then starts running at full speed again. (THE PAUSE IS NOT INTENDED, AND IS THE PRECISE PROBLEM EXPERIENCED.)
<br />
Server Configuration:
- Apache Web (HTTPS) Server - configured for AJP Proxy to Tomcat Java App Server
- Main page hitting AJP to Tomcat
- Embedded Resources (images, .js, .css, flash movies, etc.) served directly from Apache docroot
- Tomcat Server (receives AJP requests only from Apache Server)
- MySQL DB Server (receives JDBC connections from Tomcat Server only)
