--- Comment #8 from Bernhard Frauendienst <apa...@nospam.obeliks.de> --- This issue hit us quite hard when trying to upgrade from 8.0.15. An optional attribute in a very frequently used tag caused performance to drop massively (especially combined with the default non-parallel WebappClassLoader). Even though I finally found the root of the problem, it seems very hard to contain. Any developer could easily trigger the issue, and might decrease performance slowly one step at a time, without even noticing, yet causing a massive performance hit in the long run. I understand that the situation is tricky due to spec requirements, but any solution to make this behaviour more controllable would be most welcome. -- 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
