Hi,
I have a iBook G4 1GHz 256MB computer as my development machine.
Recently I installed Tiger. Before my machine was running smoothly.
Now it is noticeably slower. Waking up and application switching takes
toooooo long for instance.
I can feel your pain, having a 500Mhz Pismo (G3 laptop), with 256MB of
memory...
Is this due to the fact the Tiger kernel is 64 bit based and G4
processors are not? Or that I have 256MB RAM instead of 1GB?
The kernel is not 64-bit on any version of Mac OS X/Darwin. For
processors that support it (G5 only, so far), some user-mode programs
are 64-bit, but the kernel is not, and may not be for a considerable
while.
What you are experiencing is, I think, due to the small size of memory.
I think (although I've not been motivated to track this down) that
there is more paging going on now, possibly because apps and frameworks
are bigger.
However, I have to say, once an app is up front and in control, my
overworked Pismo feels way snappier than earlier versions of Mac OS X.
I can churn CPU cycles like mad with long-running math computations,
and still build large C++ apps in Xcode fairly quickly. The only time
things bog down is when gcc decides to expand its size to double the
amount of memory I have. But that's C++ for you.
Or, in short form: invest in more memory :-}
Regards,
Justin
