Load testing toolkit

Collection of open source tools for debugging, benchmarking, load and stress testing your code or services.

NOTE: Unfortunately I've found this original awesome collection too late: awesome-http-benchmark.
Feel free to follow and contribute to it instead of this collection, which remains my personal variation and working copy.

In alphabetical order.
