Comparison to other tools

A short, shallow and somewhat incomplete comparison to other similar tools.

Tools

wrk/wrk2

Excellent tool and strong competitor indeed. Pros:

• Both have excellent performance. In my tests (on my machine OFC) both were 1.5-2x times faster than bombardier;
• Both support scripting in Lua.

Cons:

• AFAIK, you can't build none of those on Windows (feel free to correct me).

vegeta

Haven't used this one too much. Pros:

• Really good and thorough README.

Cons:

• I'm afraid the allocation rate on high RPS is so high you can't complete even a run for 1m requests with 50k RPS (I wasn't able to do so on my machine); I would also like to point out that, maybe, the number of options is way too big. For now, I aim for a much simpler tool/functionality.

hey (previously known as boom)

Pros:

• Has a fair set of options to choose from.

Cons:

• Allocates memory proportional to number of request. In other words you can't fire some crazy amount of requests (if you really need to) and GC may have negative impact on performance;
• Throughput in my tests was generally lower. From 1x to 2x, but in some cases hey was faster (maybe, I'll investigate on this one in the future).

Goals of bombardier

To sum things up, I want my tool to be:

• Simple too use, but not overly so;
• Fast;
• Reliable;
• hassle-free building on Windows.
