From 25e410b743be45f7ed57457c1d3cd2066652085b Mon Sep 17 00:00:00 2001 From: Richard Purdie Date: Fri, 23 Aug 2013 15:55:21 +0100 Subject: bitbake: event/msg: Add primitive server side UI log record filtering Currently one of the bigger bottlenecks in bitbake is passing all the log messages over IPC to the UI. This is worthwhile if the UI is going to use them, pointless otherwise. The memory resident bitbake suffers from this performance issue particularly badly. This patch filters the log events on the server side with the global log levels and hence reduces the traffic. This speeds up parsing (18.5s down to 17s) and bitbake general command overhead is reduced (7.3s for a NOP to 6.2s). What isn't added here is general event filtering or the ability to change the log levels once set. Provision is made for adding this in a follow up patch though.
