--- Comment #8 from Mark Thomas <ma...@apache.org> --- Just to note that the performance issue with unknown charsets wasn't memory related. It was lock contention. Bug 51400 has the details. Can you provide some context around why 31ms is significant for the use case you are considering? It doesn't seem significant for the typical use cases we see. I do plan to look at the first option I described in comment #2. There are a few things on my TODO list so if you wanted to re-work your PR in that direction it would certainly help progress things. Another thing worth doing is testing with a more recent JVM to see if the original issue still exists. If it doesn't, we have a very simple solution available - remove the cache entirely. -- You are receiving this mail because: You are the assignee for the bug. --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@tomcat.apache.org For additional commands, e-mail: dev-h...@tomcat.apache.org
