Eclipse Helios (and probably all previous versions) uses only 192m when 512m is specified in -Xms and -Xmx Why?

This is the vmargs string that I have added to the Windows开发者_Python百科 Target for Ecipse.exe. In spite of adding this the memory that eclipse takes up in the Windows Task Manager is 192m. Why?

C:\Helios\eclipse.exe -vmargs -Xms512m -Xmx512m -XX:PermSize=128m -XX:MaxPermSize=128m

How to block 512m of memory on Eclipse startup itself?

Thanks for your replies.

This should work. You can also try putting the settings in eclipse.ini. See here.

This page claims that the default is 384M (for Indigo at least). Could you also try Indigo?
