Hello Joel,

so i think that your problems is due to bad design decisions caused by
lack of experience. two weeks ago when you skipped my suggestions
about improving this design and answered that you will use "systematic
approach", i foresee that you will fail and say that Haskell is a bad
language
Yes and no. The systematic approach that I used was profiling the
serialization code and tweaking all that I could. I saved my profiling
reports after each run and tracked the changes that I made. I will blog
about it after Simon M. comes back and suggests how to squeeze the last
bit out of it.
Regardless of this, it looks to me like I could easily have around 4Mb of
network traffic per second with about 4k threads and complicated nested
structures to serialize and deserialize. Trying to tackle far less data
suggests to me that it's not gonna happen. So I will try to take this as
far as I can in Haskell, once I have the heavy artillery to back me up. If
the results are good then I will use them in later applications of the
same nature but in the meantime I'm rewriting this particular app in
Erlang.
Sounds familiar ?:)

Similar experience with Erlang about 5 years ago :0)
