Bela Ban commented on JGRP-484:
-------------------------------

Measure performance of ilog.isTraceEnabled() first, maybe perf has improved

>          Issue Type: Feature Request

>             Fix For: 2.6

> For performance reasons, JGroups caches log levels as follows:
> boolean trace=log.isTraceEnabled();
> // later:
> if(trace) {
>      log.trace(...);
> }
> While caching created a measurable performance increase, it also disabled the ability to change the log levels at runtime (example: JBoss' log4j.xml, which is re-read every 60 secs).
> Investigate how to have both good performance and dynamic runtime configuration of log levels. E.g. signal to enable logging ?
