Hi folks,
We config the java -Xms and -Xmx with the 512MB. In Unix, java will make 512MB swap
every time we make a System Runtime call. Therefore, we need to lower the -Xms to
64MB and -Xmx remains 512MB so that it will not run out of swap space if too many
threads making the System Runtime
Howdy,
In Unix, java will make
512MB swap every time we make a System Runtime call.
I don't think so: can you prove the above?
Will this
hurt the Tomcat preformnace?
Lowering -Xms will only slightly degrade performance during the allocation
phase. The effects are negligible during that

If you run top, and make a servlet to call a System Runtime. Then, use
Jmeter to hammer it. You will see the swap disk is create the same
size as
the -Xms for each
to see
this one happen...
What do you mean by call a System Runtime ?
