Dynamic ContentTest: Perl CGI
Thistest was conducted with Perl script called printenv.pl that prints the CGI environment.
CGItuning 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.
Thefollowing table shows the CGI tuning settings used in the dynamic content test for Perl
CGI.
TABLE6–9 CGITuning Settings
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
Thefollowing table shows the results for the dynamic content test of Perl CGI.
