From 6f3cc77bb52349b1b88d0dd6edd2ba77141bc7f6 Mon Sep 17 00:00:00 2001 From: Vijay Pandurangan Date: Sat, 19 Nov 2011 11:30:44 -0800 Subject: This change stops sleekxmpp from spending huge amounts of time unnecessarily computing logging data that may never be used. This is a HUGE performance improvement; in some of my test runs, unnecessary string creation was accounting for > 60% of all CPU time. Note that using % in a string will _always_ perform the sting substitutions, because the strings are constructed before the function is called. So log.debug('%s' % expensiveoperation()) will take about the same CPU time whether or not the logging level is DEBUG or INFO. if you use , no substitutions are performed unless the string is actually logged --- sleekxmpp/plugins/xep_0199/ping.py | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) (limited to 'sleekxmpp/plugins/xep_0199/ping.py') diff --git a/sleekxmpp/plugins/xep_0199/ping.py b/sleekxmpp/plugins/xep_0199/ping.py index de7f5688..f8ae4018 100644 --- a/sleekxmpp/plugins/xep_0199/ping.py +++ b/sleekxmpp/plugins/xep_0199/ping.py @@ -118,7 +118,7 @@ class xep_0199(base_plugin): Arguments: iq -- The ping request.
