Subject: Shell Script based test tool for Squid Proxy Server
In my endeavour to achieve the best performance from squid proxy server and for doing a load test, created a shell script tool. The script uses Apache HTTP Server Benchmarking tool.
Basically this script shall best run on
Named it as LinTool
- Bash version 4.3.0 & above. This is because the same script observed some syntax error in bash ver. 3.1.17.
- Apache HTTP Server Benchmarking tool version 2.3 and above. The option -r [ - Don't exit on socket receive errors] was missing in version below 2.3,
