Swap partition size
The swap partition size depends on the amount of RAM you have installed, and the OSX version you use. 10.3 is much more swap hungry. Until 10.2 swap files were created in 80 MB each. They must have a new algorithm now as swap files are created like this:
Swap partition size
swapfile0 64 MB
swapfile1 64 MB swapfile2 128 MB swapfile3 256 MB swapfile4 512 MB see my post in the other thread, this kind of pattern will use only 64+64+128+256 == 512MB on a one gig swap partition since the 512MB chunk will likely require just a little too much space. -folkert. ---

"hexdump -n 4 /mach_kernel" is much cleaner. :)
As for the main thread, use Swap_Relocator: here Ignore all the n00b comments that claim it doesn't work in 10.3.x. It does.

The reason I opted for UFS over HFS+ was overhead. There is no need for a journaling file system on your swap partition. Journaling your swap file system will only hinder a systems performance. If the system were to crash there is no reason to have the swap journaled for recovery.

You can turn HFS journalling off, which I do. And the comment about fragmentation not being a problem on a swap partition is still relevant. If you're smart and put nothing else on that partition, it essentially gets cleaned out each time you reboot.

I agree with Justin's statement.

Are you ure this is a Rule? I have an original 12" alBook with ony 640 MB of RAM and I typically get (this is not from my system right now, as I rebooted this morning and it has not gone this high yet)

There are a ton of debates on how big a swap partition should be. The overwhelming majority in the BSD community (and one that I've always used on my servers) is to make the swap twice the size of available RAM. Your mileage may vary....

I am afraid that this is nonsense. I have often had more than twice the size swapfiles than my RAM - and I even have a GB in my PB, and I cannot understand why it should not exceed that when your open applications need more memory than what you have.
Swap partition size only 2X - wrong!
not true at all! |
