No yet. Have you the sendfile active? Like:
INFO: APR capabilities: IPv6 [true], sendfile [true], accept filters [false], random [true]
we had a somewhat similar problem on solaris 10 where the 2.0.9 native package made all http & ajp requests really slow. suspect there is some solaris specific apr bug in the version bundled with 2.0.9? we compiled / replaced the apr versions in 2.0.9 with the latest apr versions ( apr-1.4.5 / apr-util-1.3.12 ) and everything works fine. note, u will need to recompile libtcnative-1.so.0.1.20 again, even though the version is the same because of dependencies on the apr.
We did the same thing as Frank S (Ankur Patel was in my group) and had successful results. Will JBoss be incorporating this update into the next release?
