Hello Wolfgang,

First thing to take in account is the computer RAM memory limit so you 
shouldn't assign a memory higher than or equal to this one.

Moreover, it must be taken in account that other applications and even 
the Operative System need memory too.

For instance, if the computer have 1GB RAM memory and Windows need 500MB 
to run, you should assign at most 500 MB to gvSIG. If the computer had 
2GB RAM memory, it would be possible to assign even 1024MB.

It is possible to force the computer a little (for instance printting 
something high) assigning more memory than advisable one (near RAM limit 
and leaving for the Operative System less than it needs). In this case, 
the Operative System takes memory from the hard disk and everything runs 
so slowly.

I hope to be helpful
