Client performance differences between Windows and Linux

[Ivan Rancati <iv...@sharpmind.de>]

hello,

I was wondering if, on equivalent hardware, there might be a difference 
in using JMeter from a Windows 2000 or Linux RH9 client.
Does anybody have experiences to share?
This is only about Java VM performance and network throughput, I don't 
mean to start a "Windows vs Linux" war on this mailing list.

btw, thanks to the authors for an excellent testing tool and prompt support

Re: Client performance differences between Windows and Linux

I've used my Sun X1, RedHat and windows XP with JMeter + jdk1.4.2.

I see no performance difference worth noting. the only real reason to
use unix is to be able to ssh/telnet into a system easily and start
jmeter in non-gui mode for distributed testing.

the I/O performance between OS is not significant. if I/O is important
to you, I would recommend getting a gigabit ethernet, or put multiple
ethernet ports on the server and client systems.

In general, I/O is a significant bottleneck for stress/load testing.
To give you an example, my X1 and linux servers both have dual
ethernet ports.

If I use the same ethernet port for jdbc queries and stress testing
(i.e. http requests), the max through from JMeter's perspective is
basically 50% compared to running the jdbc queries through a second
ethernet port and switch. In practice, using multiple ethernet ports
and switches does provide significant increase in sustained
throughput. For burst traffic, there's not much difference.

I hope that helps.
