Thanks Jonathan, Joaquin,
Sorry, I found logback.xml caused the difference.
I changed logging level TRACE and the maxFileSize of debug.log in
conf/logback.xml.
logback.xml of C* by yum (changed):
logginglevel: TRACE
maxFileSize of debug.log: 500MB
logback.xml of C* by git (default):
loggin

noisy neighbors may be affecting your performance on different AWS
instances.
You should verify that you're using the same version of Java during both
tests.
Also, ensure that you're using the same test instance (
Hi all,
I'm trying a simple performance test.
The test requests select operations (CL.SERIAL or CL.QUORUM) by increasing
the number of threads.
There is the difference of the performance between C* installed by yum and
C* which I built by myself.
What causes the difference?
I use C* 2.2.8.
