Subject: tbench as a load - DDOS attack?
Date: Sun, 16 Feb 2003 10:07:25 +1100 [thread overview]
Message-ID: <200302161007.25149.kernel@kolivas.org> (raw)
Zwane M suggested using tbench as a load to test one of his recent patches and
gave me the idea to try using tbench_load in contest. Here are the first set
of results I got while running tbench 4 continuously (uniprocessor machine):
tbench_load:
Kernel [runs] Time CPU%
test2420 1 180 38.9
test2561 1 970 7.7
This is a massive difference. Sure tbench was giving better numbers on 2.5.61
but it caused a massive slowdown. I wondered whether this translates into
being more susceptible to ping floods or DDOS attacks? You should have seen
tbench 16 - 3546 seconds!
comments?
