Remko Popma updated LOG4J2-1179:
--------------------------------
Description:
_(Work in progress. Still thinking this through.)_
The web site currently has two performance pages:
*[Performance|https://logging.apache.org/log4j/2.x/performance.html]*
A general performance page comparing Log4j 2 to Logback and Log4j 1. This page
is not part of the manual, and the only link to it is from the About top page.
This page covers:
* logging turned off (with is<Level>Enabled)
* Parameters vs. String concatenation
* Synchronous logging (to unspecified appender with unspecified layout) - stale
(log4j-2.4 improvements are not included)
* Filters (ThreadContextMapFilter and MarkerFilter)
* Environment: MacBook Pro laptop specifying clock speed but omitting OS, JDK
and # cores.
*[Async Loggers
Performance|https://logging.apache.org/log4j/2.x/manual/async.html#Performance]*
Intended as in-depth analysis of async loggers. Mostly a comparison of Log4j 2
to Logback and Log4j 1. This page covers:
* Synchronous vs. asynchronous logging (stale: synchronous log4j2 logging
especially has improved a lot since 2.0-beta5)
* Async Logger vs. Async Appender
* Cost of logging location information (may be improved with LOG4J2-1029)
* Separate analysis for throughput and latency
* FileAppender vs. RandomAccessFileAppender (should not be on this page)
* Environment: laptop Windows 7 with JDK1.7 on 4 cores and enterprise server
Solaris 10 with JDK1.7 on 16 cores
*TODO: dedicated Performance section on web site*
I would like to add a Performance section to the site (accessible from the nav
side menu). Not sure if this should be part of the manual or under APACHE
LOG4J™ 2 in the nav side menu.
This section would include and reorganize what we already have, and in addition
have sections (separate pages?) on:
* General tips to improve logging performance
* Cost of various layouts (HTML, XML, CSV, Pattern)
* Cost of various Pattern Layout options
* Cost of various appenders (File, RandomAccess File, MemoryMapped File,
Console, Rewrite, other?) TODO: decide on layout for these tests.
* Cost of various APIs/wrappers (SLF4J, Log4j1, JUL, Commons Logging)
