Subject [brutus] webapp - why?
Date Thu, 08 Jul 2004 08:52:56 GMT
Hi gang!

could someone explain to me exactly *why* we're running forrest as a 
webapp? It's a relatively big resource hog...

Looking at our resource usage, we have the following:

load average: 0.97, 1.01, 1.31
Tasks: 112 total,   2 running, 110 sleeping,   0 stopped,   0 zombie
Cpu(s):  23.9% user,   2.2% system,   0.0% nice,  73.9% idle
Mem:   2069676k total,  1994204k used,    75472k free,   253520k buffers
Swap:  4289240k total,    14164k used,  4275076k free,  1032492k cached
 
 

   PID USER      PR  NI  VIRT  RES  SHR S %CPU %MEM    TIME+  COMMAND
22386 gump       9   0  105m 102m 9984 S  0.0  5.1   0:08.37 java
22387 gump       9   0  105m 102m 9984 S  0.0  5.1   0:00.97 java
22388 gump       9   0  105m 102m 9984 S  0.0  5.1   4:28.08 java
(...)

in other words, that's a lot of tomcat processes with a lot of resident 
memory. From just hitting refresh a lot against the webapp, I suspect 
brutus actually slows to a crawl if -- for example -- there's more than 
a few concurrent users, or some web bot is indexing the gump space.

cheers,

- Leo
