I should also point out that the vast majority of the latency in opendkim processing is very likely DNS delays. There's very little we can do in the source code to deal with that.

Have you done any profiling to see where it's bottlenecking?

There are some libmilter build-time features that do things like restrict libmilter to a fixed-size worker pool rather than making one thread per client. I don't recall how much faster that gets it going, though.

There's an open item to improve the speed at which canonicalization occurs, which is where libopendkim spends most of its time. I'm hoping to do that for the next release.

Hi All!

Is there any way to optimize opendkim to work with high performance systems/servers. For example, can I increase number of processes of opendkim or make it work faster and better?
