I did that. ULE seems to be slightly faster - at least accoring to ab which
was benchmarking the critical application on the system.
See my original post for numbers.

Using ULE instead of 4BSD improved performance.
Not using HTT decreased performance.
Using 4-STABLE instead of 5-CURRENT decreased performance.

During the last two weeks ab showed another boost of performance
(up from 11.5 to 11.96-12.00 which is slightly more than 4%) on 5-CURRENT.

Test is mainly asking apache via ab to execute a very_large(tm) perl
program with lots of includes (compile, run) and return the result.
Call is via cgi, not mod_perl. Please don't comment on that.
