Dynamic Content Test: Perl CGI
This test was conducted with Perl script called printenv.pl that prints the CGI environment.
CGI tuning settings were applied to the server. The goal was to saturate the cores on the server
and nd out the respective throughput and response time.
The following table shows the CGI tuning settings used in the dynamic content test for Perl
CGI.
TABLE6–9 CGI TuningSettings
Default Tuned
idle-timeout=300
cgistub-idle-timeout=30
min-cgistubs=0
max-cgistubs=16
idle-timeout=300
cgistub-idle-timeout=1000
min-cgistubs=100
max-cgistubs=100
The following table shows the results for the dynamic content test of Perl CGI.
