: How to replay traffic to web server from logs to profile / benchmark web app under real load? Is there a way to get recorder real network traffic to web server, e.g. from web server logs

This may do what you want:
patrick.net/sprocket/rwt.html
It has an ultra-simple proxy for recording traffic, and an even simpler perl script for playing it back!

Depending on the scale, you will need a specific software, though a specific software is recommended for any performance/load/stress tests hence they can provide better results.

For medium traffic, I can recommend Apache Jmeter, or Selenium RC. I think replay Apache HTTP Server (yes, this is the fullname from our famous Apache) logs is easier to do into Apache Jmeter.

Why would "real" data give you more information than a simulation that scales until the server breaks? At the very least you should be able to amplify the load signal from the load data to give a range on the performance... Also, seems like the log data would only profile the request, not the response rate from the client request, meaning one client request to close the connect super fast, the other might lag.

If you want to record and replay real traffic, I think the most direct solution would be to log full request headers to a file and then use a solution like curl to "replay" the requests against your webserver.
