Web-bench

Web Bench is a straightforward and user-friendly tool designed specifically for benchmarking WWW or proxy servers. It makes use of fork() for emulating multiple clients and supports HTTP/0.9-HTTP/1.1 requests. This benchmark may not be very realistic, however, it is still efficient in testing if your HTTPD can handle a considerable number of clients at one go (try to run some CGIs) without causing a system crash.

Furthermore, Web Bench displays the metrics of pages per minute and bytes per second, thus giving you an instant overview of your server's performance. If you're looking for a more aggressive testing mode, just enable the -f switch.

In addition, the latest version of Web Bench includes the capability of building with both Gnu and BSD make. Overall, Web Bench is an ideal software for developers and IT professionals to test their web or proxy servers, and ensure they are capable of handling large amounts of traffic without causing downtime or glitches.
