Siege

Install

apt-get install siege

Run

siege -b -c 1000 -t 30s example.com

In above command:

  • -c stands for concurrency. We are using 1000 concurrent connections.
  • -t specifies time duration. We are using 30 seconds
  • -b is to run siege in benchmark mode. Without it, siege inserts delay between 2 requests.

  1. Greetings,

    When I run this command I get the following error:

    [error] descriptor table full sock.c:108: Too many open files

    I don’t get the error when I reduce the concurrent connections to 500 or 750. Is this something that can be changed with a configuration change, or is this due to limited resources?

    Thanks very much.

    Jim
