We are having performance problems which we traced to overhead from our logging. Each log statemement is taking around 200 ms. The details of the logging configuration are:
Log4j 1.2.8 with RollingLogFileAppender http://www.nabble.com/user-files/267/test_jsps.zip test_jsps.zip File Description 64-bit Linux 32-bit Windows logging.jsp Log 1000 iterations using only Log4j 93 ms 0.41 ms file-IO.jsp 1000 iterations small file read using pure java file utility package 0.01 ms 0.13 ms file-IO.jsp 1000 iterations writing to servlet logfile utilizing J2EE servlet API 1.67 ms 2.82 ms Log4jPerformanceTest.java Log 1000 iterations using only Log4j 0.81 ms 0.26 I have attached the source code of each test. As you can see the performance for a simple JSP which logs 1000 log statements using log4j is over 200 times slower on the 64-bit Linux vs. the 32-bit Windows machine. Does anyone have any advice? -- View this message in context: http://www.nabble.com/Log4j-1.2.9%2C-64-bit%2C-Websphere-Performance-Problems-tf2088247.html#a5755612 Sent from the Log4j - Users forum at Nabble.com.
