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?
