Hi, I've been suffering performance issues with CIL recently. 30% of the time was spent in garbage collection.
[Not sure if this figure is significant since I still spend 30% of my time garbage-collecting, but it's a shorter time now ;-) ] The issue basically boils down to a lot of partial evaluations, pushing the GC under heavy-load. I'm currently patching cil.ml extensively (well, the visitor part at least) and reduced the number of allocated words by half on my benchmarks. [By the way, ocamlutil/stats.ml is broken on 64bit architectures, the figures returned by printM in Stats.print should by doubled. I'll send a patch for this one too.] I still have an awful lot of major collections but I think I'm on the good way since there are far less allocations. I'll provide a unified patch on this list soon but curious people could look at the latest patches (using darcs) here: darcs get http://www.pps.jussieu.fr/~kerneis/software/repos/cil/patched More information on the general issue and work-arounds here: http://ocaml.janestreet.com/?q=node/30 Regards, -- Gabriel Kerneis ------------------------------------------------------------------------------ Register Now for Creativity and Technology (CaT), June 3rd, NYC.
