Hi Guys
For the last couple of days I tried to find some information regarding
tuning of Tomcat 5.5 Online or as a Book but couldn't find much. Where
could I get any information about this ?

We migrated to tomcat 5.0.28 from jserv, which is affecting the performance

Hi, does anybody know which parameters are involved in tuning the

You can tune CoyoteConnector acceptCount and timeout values.
acceptCount=10 should be fine, though you never know (test test test :-)
timeout value (in seconds) shouldn't
So nothing related to the jk2 connection between Apache and TC can be
tuned? How many connections will Apache make? Auto grow?
