Dear magnolians We are experiencing performance issues on our magnolia webapp. The change from one static page to another takes too much time (around 5 seconds). After we have enabled the garbage collection logging (jvm options) we see that there is a lot going on. Here is an example from our log file:
35937.240: [GC [PSYoungGen: 214496K->192K(209728K)] 512388K->298084K(752256K), 0.0138620 secs] [Times: user=0.03 sys=0.00, real=0.01 secs] 35953.744: [GC [PSYoungGen: 209728K->128K(204992K)] 507620K->298020K(747520K), 0.0138240 secs] [Times: user=0.03 sys=0.00, real=0.01 secs] 35978.276: [GC [PSYoungGen: 204992K->160K(200576K)] 502884K->298060K(743104K), 0.0148430 secs] [Times: user=0.02 sys=0.00, real=0.02 secs] 35994.767: [GC [PSYoungGen: 200544K->128K(196160K)] 498444K->298036K(738688K), 0.0137840 secs] [Times: user=0.03 sys=0.00, real=0.02 secs] 36019.252: [GC [PSYoungGen: 196160K->160K(192064K)] 494068K->298068K(734592K), 0.0139570 secs] [Times: user=0.03 sys=0.00, real=0.01 secs] 36035.743: [GC [PSYoungGen: 192032K->128K(187968K)] 489940K->298036K(730496K), 0.0148920 secs] [Times: user=0.03 sys=0.00, real=0.02 secs] 36052.235: [GC [PSYoungGen: 187968K->128K(184064K)] 485876K->298036K(726592K), 0.0141940 secs] [Times: user=0.03 sys=0.00, real=0.02 secs] 36076.664: [GC [PSYoungGen: 184064K->160K(180352K)] 481972K->298068K(722880K), 0.0137670 secs] [Times: user=0.03 sys=0.00, real=0.01 secs] 36093.133: [GC [PSYoungGen: 180320K->128K(176640K)] 478228K->298036K(719168K), 0.0150890 secs] [Times: user=0.02 sys=0.00, real=0.01 secs] As you can see, the garbage collector is working all the time which – in my opinion – should not be the case. Based on this I guess that our application has some memory leaks. We will investigate that next. Now, how is the default behavior of the garbage collector in a standard web application? What is your experience about this? Thank you for your response in advance!
