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. This email sent to site_archiver@lists.apple.com
