Hello,<br>
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.<br>

Thanks,<br>
