iCab uses temporary memory for the most part. So the *only* time you should increase its memory size is if you have a *specific* plug-in that requires it (is not temp-memory aware). FWIW, I often have a dozen pages open at a time in iCab, using the default allocation of only 3000K!
Dan...temporary memory? There's Ram and there's HD space (VM). Does icab have a facility other prgms have not to allot more memory on the fly?
The relationship between real memory (RAM) and virtual memory is maintained way-deep in the OS, within the software memory manager. We're talking about (generic) memory allocation, as in how the OS gives applications access to blocks of memory (real or virtual; the application doesn't know and doesn't care).
The classic Mac OS allocates memory to an application two ways.
1. Direct allocation during program launch. This is what you see in the Get Info window.
2. Dynamic temporary allocation off the system heap.
The latter technique lets a program be sized (1) for "average" operations. Then, when it needs extra memory - for bigger windows or whatever - it just asks the OS on the fly for it (2).
Most applications written for OS 8.6 or later use temporary memory.
iCab uses temporary memory for just about everything. But some plug-ins, Flash 4 and 5 especially, don't know about temporary memory. They operate by grabbing memory from the direct allocation.
Thoth uses temporary memory a lot! In fact, you can almost totally kill its performance by increasing it's preferred memory size!
The Finder uses temporary memory for most operations.
Some printer drivers steal direct allocation from the Finder -- which is why their installers often increase the Finder's preferred memory size then force a reboot.
