[AusNOG] Load Testing Tools?

[Alex Samad - Yieldbroker]

Hi

I pushed 9.5-9.8Gb/s from a VM, recently … with iperf tcp and udp..
Centos 6.5
VMWare 5.5
vmxnet3 nic
host 1.8G cpu, 2 x PG of 2 x 10G nics

+1 for iperf, it’ll run 10gbps fairly well too even on commodity desktop hardware with the right cards ☺

Thanks,

Apache jmeter is immensely useful. It can be used to throw load at HTTP/HTTPS and a lot of protocols over top of that (SOAP/XML, JDBC, AJP etc) as well as do generic TCP connects (with auth and custom data), SMTP, LDAP queries, POP3, IMAP ... and probably more which I've never used. Can function distributed also, e.g. tests distributed from one client to multiple jmeter servers.

It can't do UDP natively, but it would be fairly trivial to front RADIUS auth with a HTTP interface that jmeter can talk to. e.g. Basic auth against a bunch of servers with Apache/mod_auth_radius.

I've used iperf/jperf for generic TCP/UDP data to test QoS etc. Could almost certainly be pushed to 10G with enough CPU or multiple hosts.

Hi all,

I'm curious what load testing tools (commercial or home grown, if any) people use for generating network & systems load to test throughput & response times.

Eg for capacity testing, performance testing after a network or software change, etc.

More specific examples would include radius server testing packets per second (to cater for a brown out disconnect / reconnect event), or proxy server testing peak requests per second, or throughput testing an upstream 10Gbit link from a carrier, etc.


prk.
