psping to localhost - improve throughput

  • 772

I'm using following psping command to measure the bandwith throughput for localhost on a physical server

psping -4 -b -l 8k -n 20000 localhost:1234

The throughput is around 150MB/s wich isn't all that bad but for an ipc over tcp problem we are having with an ODBMS running on the server, we decided to try the application on a standalone pc.

The performance on that standalone pc is far better than that of our server. It's throughput to localhost gets up to 800MB/s what I believe to account for most of the performance difference.

Does anyone know how to improve the localhost throughput on the server?

  1. You are comparing a 6-year old server to a 3 year old PC with a much faster clocking.

    If you can tune your DB so it will use all cores you will propably solve your local performance problem.

    I do not think you have an IPC issue.
