-Xms and -Xmx

[George Luiz Bittencourt]

Hello,

I see a lot of people in the Java world saying to configure both the -Xms
and -Xmx parameters as the same value.
However I don't see a reason for that. I come from the .NET world where we
do not configure theses parameters and it works perfectly.

My question is: what are the disadvantages of not configuring them as the
same value?
I want to visualize using top or task manager the real use of memory of my
Java applications.

Thanks,
