Performance degradation after the firts million requests
--------------------------------------------------------
Key: CLEREZZA-347
URL: https://issues.apache.org/jira/browse/CLEREZZA-347
Project: Clerezza
Issue Type: Bug
Environment: java version "1.6.0_20"
OpenJDK Runtime Environment (IcedTea6 1.9.1) (6b20-1.9.1-1ubuntu3)
OpenJDK 64-Bit Server VM (build 17.0-b16, mixed mode)
Reporter: Reto Bachmann-Gmür
After installing the java-ssp-ttl prototype sample I do the following to
measure performance
for i in `seq 1000`; do echo round $i; ab -n 10000 -H "Accept:
application/xhtml+xml" -c 100 -A admin:admin
http://localhost:8080/greeting/list; done
Depending on the heap settings of clerezza the performance starts degradating
massively after a period of relative constant sped.
Degradation starts at (> 10000000 = no degradation observed)
-Xmx200m: > 10'000'000
-Xmx600m: > 10'000'000
-Xmx1g: 610'000
-Xms1200: 750'000
-Xmx2g: 1'300'000
-Xmx3g: > 10'000'000
no mx argument set (on a machine with 5964MB of ram): 970'000
Repeated measurement with the same mx-value yield to almost identical results.
