[Haskell-cafe] [ANN] wrecker - An HTTP Benchmarker

[Damian Nadales]

Good that the bottle neck is clearly identified.

On a related topic, we're starting to benchmark our web services, and we're
using http://gatling.io as benchmarking tool. It is Scala based and I'd
like to write the benchmarking program in Haskell instead. However I need a
tool that can record the duration of each requests, and maybe aggregate
them and export this to some format (I don't care about the plots right
now).

I don't know of wrecker has this capabilities or maybe there are other
tools that the Haskell community use for this purpose. Any hints?
