Hi Toni,
It would be interesting to know where Sequoia actually spends its time.
Could you turn the CPU profiling in the JVM to get an idea of what is
going on?
Also what does your configuration look like?
Thanks for the feedback,
Emmanuel
We are doing some load test of on product using JBOSS, Sequoia and
MySQL, and in our test we have notice that sequoia get a very big,
big, big quantity of CPU...
Look top in machine where the service is processes ( nearly 150%cpu ),
we are talking about servers with 2 CPUS :
top - 14:36:31 up 25 days, 22:28, 2 users, load average: 6.87, 6.53,
3.66
Tasks: 104 total, 1 running, 103 sleeping, 0 stopped, 0 zombie
Cpu(s): 59.0% us, 8.1% sy, 0.0% ni, 29.6% id, 0.7% wa, 0.3% hi,
2.3% si
Mem: 8164704k total, 5899548k used, 2265156k free, 387168k buffers
Swap: 8385920k total, 0k used, 8385920k free, 3190788k cached
PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+
COMMAND
26562 sequoia 17 0 2010m 366m 14m S 150 4.6 16:28.59

21342 mysql 16 0 544m 371m 4872 S 37 4.7 43:01.14
mysqld
And this in the BE which is not processing any traffic :
top - 14:42:00 up 25 days, 22:33, 2 users, load average: 3.99, 4.57,
3.67
