From: Rafał Miłecki Date: Fri, 10 Feb 2017 13:44:39 +0000 (+0100) Subject: Avoid duplicated iteration over services when announcing X-Git-Url: http://git.openwrt.org/?p=project%2Fmdnsd.git;a=commitdiff_plain;h=e47f6cf16e6d998670be00cf241a0224ccbfb713 Avoid duplicated iteration over services when announcing In function service_announce_services we iterate over services and handle every single one so calling service_reply which also iterates doesn't make sense. In simple cases it was just wasting CPU cycles. We got service, we were passing its name and we were looking for it again comparing names. In cases with one service available on few different ports it was worse. For every iterated service we were announcing that one and all other sharing the same name. It resulted in sending n^2 records.
