SpeedySu is a modification of SpeedyCGI (a.k.a. PersistentPerl) so that it works with suEXEC-enabled Apache Web servers. Both Apache 1.3.x and 2.y running on UNIX systems are supported. SpeedyCGI speeds up Perl scripts (CGI or not) so that they remain running persistently, thus reducing the startup times of subsequent executions. SpeedySu extends SpeedyCGI by allowing ~UserDir CGI scripts started by Apache execute with the privileges of their owner user. SpeedySu contains other improvements in addition to suEXEC support.
