I set up just a basic DVD folder encode on Handbrake 0.94 with Apple TV settings on my dual core G.5 2.3ghz Xserve, just to see what would happen. 7hours later . For comparison I also have my Dual Core i5 2.3ghz MacBook Pro encoding a DVD folder using the same settings in Handbrake o.98 will take 1.5 hours. To DVD encoding, my Xserve says no apparently . Real world comparison? My MacBook Pro is a bit more than 4.5 times faster for the same CPU clock if we look at time it takes to complete a task. But this is not accurate, as it does not take into account disk access time, lets look at frames per second where my Xserve is chugging away at 11frames per second and while I'm typing here my MacBook Pro is ticking over 25 frames per second. Anyway, I am likely to convert 3 or 4 DVDs with Handbrake on my MacBook while doing other tasks while my Xserve will do just 1 with the only thing open being Handbrake in the same time. Ok, so I have a few DVD folders left to convert and this will make the process a little bit faster, it's the tortoise and the hare, but if I had to do this all with my Xserve? It would take 2 or 3 days for what is going to take 8 hours. This is an interesting comparison for what a machine with two 2.3ghz physical cores gets you in 2005 from Apple vs. what a machine with two 2.3ghz physical cores gets you in 2011 from Apple. 6 years is an eternity in computer technology. I do wonder though, can I make this task faster by installing a SATA2 controller? I need to do some more research as to how the drives connect to the motherboard in the Xserve. I guess with some longer data cables routed to the PCI slots rather than the opposite side of the board where the SATA ports are I could do it. After doing some inspection here. http://d3d71ba2asa5oz.cloudfront.net/43000231/images/qt42600k4rdnk.jpg But how much difference would it make and how much of this problem is CPU related.
