Well, I haven't seen that categorically stated - but even if it were true for Snow Leopard, it does show the direction that Apple is taking OS X. So, maybe 10.7 will give us a new file system?

To be fair ZFS really shines as a server file system, especially in a multi-disk systems. For desktops/single disk systems, its features aren't particularly special. However, for developers its handy to have access to the same FS used on servesr and you would think supporting one FS across both desktop and server OS's would be worth the effort.

True, and another poster here (Aquafire, I think) pointed out that the current Mac file system has been around for a comparatively long time.

Now I'm getting excited about Snow Leopard.

Not only is it very likely that PPC support will be dropped, but Apple are taking code that is duplicated within many apps and putting it into a central repository accessible to all apps. The result is that common apps are reduced by some pretty incredible percentages:



(MacUser article here and Roughly Drafted article here)

This will certainly make Snow Leopard much less greedy for memory, but could it result in a faster system? Much faster? Twisted Evil

Will it?

This is moving stuff from one part of the OS to another part. The strings used to be part of the app directories, they'll now be somewhere else. In so much as some strings are common to more than one application there will be some disk space savings. I don't see that it will speed things up - given that there is probably now an extra layer to go through to access the strings it might slow them down!

Ah, but if I click the 'System Memory' tab within Activity Monitor, there's a blue slice of the pie chart called 'Inactive' - data that's been called up from the HD and used, but not deleted in case it's needed again. Now if Snow Leopard keeps data in memory that can be used by many apps, then surely the number of HD reads will fall (won't they? Confused ). So maybe that's one way that Snow Leopard will have a speed advantage over Leopard.

Or maybe I'm just talking a load of over-optimistic crap. Smile
