Excessive warnings about Timer woken up late on Windows
-------------------------------------------------------
Key: QPID-2150
URL: https://issues.apache.org/jira/browse/QPID-2150
Project: Qpid
Issue Type: Improvement
Components: C++ Broker
Affects Versions: 0.6
Environment: Windows
Reporter: Steve Huston
Fix For: 0.6
The C++ broker when running on Windows, shows a lot of warning messages like:
2009-10-15 21:48:37 warning Timer woken up 15ms late
The lateness is usually between 10 and 15 msec, owing to the relative
imprecision in waking up a thread on Windows. I have two suggestions for
resolving this:
1. Change the message from warning to debug. I'm a bit concerned that,
regardless of platform, if users of a product where speed is an issue start
seeing messages about timers waking up late, they may be concerned, without any
cause probably. I'm thinking that the only people interested in this message
are those diagnosing things who may want to enable debug messages.
2. Allow a platform-specific value for the threshold at which lateness prompts
a message. For example, the current 10 msec limit is tighter than is useful for
Windows - 30msec would be better.
