svn commit: r327757 -
/httpd/httpd/branches/async-dev/server/mpm/experimental/event/event.c
Author: brianp
Date: Sat Oct 22 23:46:00 2005
New Revision: 327757
URL: http://svn.apache.org/viewcvs?rev=327757&view=rev
Log:
Use the new APR_POLLSET_NOCOPY option when creating the core pollset.
This eliminates the descriptor copying and mutex operations, and
O(n)-time apr_pollset_remove() loop when used with an apr_pollset
implementation that support the no-copy optimization.
