[Haskell-cafe] Can a GC delay TCP connection formation?

[timothyhobbs at seznam.cz]

Could you give us more info on what your constraints are?  Is it necessary 
that you have a certain number of connections per second, or is it necessary
that the connection results very quickly after some other message is 
received?

Kazu and Andreas, could this be IO manager related?

" Hello,
I've run into an issue that makes me think that when the GHC GC runs while a
Snap or Warp HTTP server is serving connections, the GC prevents or delays 
TCP connections from forming. My application requires that TCP connections 
form within a few tens of milliseconds. I'm wondering if anyone else has run
into this issue, and if there are some GC flags that could help. I've tried 
a few, such as -H and -c, and haven't found anything to help. I'm using GHC 
7.4.1.

Thanks,
Jeff
