Hi
I try to configure Cocoon and Tomcat such that the
performance is as good as possible. What I figured out already is
1) set all "check-reloads" attributes within all sitemaps to "false"
2) set all "log-level" attributes within logkit.xconf to "ERROR"
3) set attribute "reloadable" of Context cocoon within
tomcat/conf/server.xml to "false"
I guess there are more parameters to turn, for instance
how do I turn off the lookup of lastmodified of XSLT, or
is this configured by check-reloads already?
Any further tips or help appreciated.
Thanks
Michael
