SYNOPSIS

    livehttperf --help

DESCRIPTION

livehttperf is a web performance testing tool using recorded sessions from LiveHTTP headers Firefox extension.

INSTALLATION

    cpanm App::livehttperf

HOW TO USE

This tool is intended to be used to compare how the changes of your web application front/back-end impact user experience and the overall performance of your web server.

Create repeatable test scenario

Therefore you need to create a typical user session (browse a bit, add products to basket, fill some forms, let some AJAX calls to be executed), which you can then replay on the new version of your website.

I'd recommend Selenium IDE to do so.

Remember to manually add pause commands if you want to add delays between navigating to other pages.

Record live requests/responses

Execute Selenium's test case with LiveHTTP headers capturing live traffic.

Save to a file which will be used as input file for livehttperf.

Prepare web / database server(s) for tests

Start some system monitoring tool on those servers to measure impact of your test.

Install one (or both) packages:

  • sysstat

        man sar
  • procps

        man vmstat

Prepare your client server

Disable any processes that could impact the client server performance.

Use same tools as above to measure the impact of test.

Execute your tests

    livehttperf --help

Specify configuration options and run your tests.

Use LibreOffice Calc to open saved result file (XLSX format).
