Have 1.75gig and having pageouts

[Lawrance Allen Schneider]

I have 1.75 gig of ram.

Ever since I did the security and iDVD updates, I'm having pageouts.
When I run the prebind module in 'Maintain Your Mac,' I'm told that 55
items failed 'prebinding.' I looked at the log and it said that some of
the files needed to be 'relinked.'

Does anyone have any idea as to what to do?

Thanks Larry

I've got 1.25 GB. It happens. It's how the system works. At the
moment, my system has been up for 34 hours since installing the last
security update. I've got 20 pageouts even though I'm only showing 173
MB in use. I also have over 14,000 pageins and one swap file taking up
a little over 76 MB.

Lots of memory doesn't mean no pageouts and no use of virtual memory.
It just means fewer pageouts and less use of virtual memory. In the
end, that means things go faster.

Besides the questionable benefit of spending 30 minutes fragmenting a
volume to hell for a minor optimization, it's a bad idea to
automatically modify executables. It's only a matter of time before a
million MacOS X computers are wiped out all at once due to a bug or
virus in the pre-binding code.

Caching dynamic link data should be done elsewhere. It could be in RAM,
it could be in a system database, or a more efficient method could be
used, but it shouldn't be stored in the executable itself.

If it's taking 30 minutes, you've got problems. If it takes 10 minutes
you've got problems. And it's not like it stops you from working in the
general case while it's doing it.

Well, "a lot" is fairly subjective, but since most of the several Macs
that I use are, in fact, software development systems (and none of them
especially high-end), I feel confident reiterating my assertion: If it
takes 10 minutes, you've got problems.
