I deal with a lot of network devices for ThinkComputers and split the duties with Sean for BIOS LEVEL.
We generally run a few tests:
I may have omitted a test or two, but I'll send a link to this thread to Sean so he can add to it, too.
How do others test network performance?
Devices I've tested are primarily routers, switches/hubs/bridges, and NAS devices. I have yet to get my hands on a Killer NIC.
I was thinking about a test suite in which one computer runs a program which performs each of the tests automatically, but handles the file/RAM management operations.
What do you think?
We generally run a few tests:
- Disk -> network -> disk via SFTP, SMB, CIFS : tests bandwidth/throughput with bottlenecks in protocol, CPU, and hard disk performance
- Disk -> network -> disk via ye olde netcat : Bottle neck in hard drive (and IP stack, but it's fairly consistent across Linuxes, I think)
- RAM disk -> network -> RAM disk via netcat : Bottleneck is RAM speed
