Return ImmediateFlush and perhaps buffering options to FileAppender
-------------------------------------------------------------------
Key: LBCORE-243
URL: http://jira.qos.ch/browse/LBCORE-243
Project: logback-core
Issue Type: Improvement
Components: Appender
Affects Versions: 1.0.0
Reporter: Petr H
Assignee: Logback dev list
Based on the "log4j performance comparison" discussion in the logback-user
mailing list:
http://old.nabble.com/log4j-performance-comparison-td31183677.html
I'd like to see at least the ImmediateFlush option back as it causes really big
difference in writing performance at our systems with heavy logging activity.
Last logback release with ImmediateFlush option is 0.9.18 and this is the one
we have to stay at due to performance reasons. We can't afford to upgrade to
later logback release or switch ImmediateFlush to true as it makes some of our
systems practically unusable.
The best option seems to be the use of FileWriter with the possibility to set
the ImmediateFlush option and also buffering (wrapping with BufferedWriter and
use of BufferedIO + BufferSize options) can help a little.
