Hi Anders!
How're you doing ?
Thanks for the suggestion. We actually have a solution in production
right now (www.besport.com <http://www.besport.com>) that relies on
netshm. Unfortunately, the serialization / deserialization is killing
the performance : about 200ms for a full request against 7ms for a
simple Hashtbl lookup on our hardware.
200 ms seems too much - Nothing takes 200ms on modern hardware. not even
on AWS :-)
Maybe the system was swapping or some other noise polluted your
statistics. Which serialization format did you use? ocaml's standard
marshaling, or did your write your own?

unacceptable segmentation faults, and before debugging this library I'd
rather learn about other approaches :)
What type of performance do you get with ocaml-everlasting?
