Thanks again Mark :-) mt> how that Map is pruned (it is currently too aggressive)
mt> if Tomcat is processing 10k req/s just keeping track of mt> the last 30s is potentially 300k streams. How to do that mt> efficiently for all usage patterns is a problem that mt> needs some thought. Sounds a bit like garbage collection. Is aging part of the process - a map/queue combo? cjb> How could the closed stream footprint be reduced? cjb> Could the structure holding a closed stream: cjb> a. Be replaced with a smaller one? cjb> c. Or did you already have something in mind? mt> A form of a). I'm looking at this now. cjb> b. De-reference other objects no longer needed? cjb> Hmm... that might lead to NPE's and thus unnecessary cjb> null checking. mt> Tried that. Lots of NPE regressions to the point that mt> I reverted the change to look for a better solution. Hey great, I'm beginning to understand! :-D mt> we have all the plumbing to correctly determine mt> relative priority [...] we don't use it to prioritise mt> streams when flow control windows are not an issue mt> I started to look at this a while ago but it gets very mt> complex quite quickly. It would be simpler if we were mt> just serving static content. Ha ha, httpd!
