Any open source "free" load and performance testing tools?

[Matt Brown]

I'm looking for a "free" tool for load and performance tests of a website.
Is Apache JMeter good? Any suggestions?

I have not used much of open source tools, check out the below link. Hope this provides your need.

I've often used JMeter; the UI is a bit rustic, but it allows pretty granular load testing.

David,

With JMeter, what is the max HTTP requests can be submitted within one second?
Is there any limitations on concurrent HTTP sessions?
Did you test long lasting HTTP session with multiple request/response (e.g., Login, AddToShopingCart, CheckOut, SubmitPayment, Confirmation, ...)?
Did you see any bottleneck due to the client computer where JMeter is running?
Any suggestions on client computer?

Thanks so much.

I have no idea. Maybe just try it.

- Is there any limitations on concurrent HTTP sessions?

Don't know why there would be; it's just cookies.

- Did you test long lasting HTTP session with multiple request/response (e.g., Login, AddToShopingCart, CheckOut, SubmitPayment, Confirmation, ...)?

Yeah, but again, it's just cookies--not rocket science.

- Did you see any bottleneck due to the client computer where JMeter is running?

No.

- Any suggestions on client computer?

No.

David,

I got a requirement to load test a web application built upon Microsoft technologies with a cluster of two Window 2008 servers.
My load test tool must be able to generate 1,000 concurrent users.

Can JMeter do it? Can a good laptop create 1,000 HTTP requests in a short period (< 1 minute) using JMeter?

[David Newton]

A thousand a *minute*? Of course. That's not even 20reqs/sec.

Still--why not just try it?
