I have lotsa RAM. When I up the memory allocation for a particualr app, I usually just enter some huge number instead of making the kb to mb calculation.

Can an apps performance decrease by allocating too much memory?

Just wonderin...

The app's performance isn't likely to decrease, but your overall computer's performance might. If you allocate a large block of memory to a single program, other programs (and/or the system) could run out. Also, I would check in About This Macintosh to make sure you really need to allocate a huge amount of memory. Generally, a program is not likely to ever need more than 150% of the default amount.

Not so fast, some times if you give a program too much memory (like Quake 3), it will not work properly (like Quake 3, crash on level load).

There are a number of programs that become unstable if too much memory is allocated.

One of them, I believe, is Netscape (and there are others) sometimes the read me's will warn of this possibility, but not always.

The actual maximum you can use per app is 999 megs. Like that's gonna be a problem...
