Mac Pro :: How To Make Performance Doubled
Apr 18, 2008
I finally bought my Mac Pro last week, and needless to say it continues to impress me. I was transferring some files from my 1tb Seagate 7200.11 to my boot drive consisting of two 74gb Raptors in software raid 0. Since i've had it, the 4gb files have always transferred at about 60mb/s, but tonight the speed somehow managed to double to a maximum of 127mb/s (and a sustained 100mb/s). Why would the transfer rate double in speed?

I searched for this up and down and for some reason can't come to a solution.
I was making a double-backup of my music folder (merely copying the folder over to another external hard drive), and I noticed my mp3 collection has doubled in size!
I've tried finding duplicates but it pulls up a very short list of the usual suspects that I know aren't dupes. I looked in my music folder directly only to see my regular mp3s with no duplicated files.
How do I get rid of these "phantom" mp3s?

I have a MacBook Pro and need it for work (music & film) but I've been using my sister's MacBook for school and it started acting up this morning.

That's the computer. The right side of the screen is black and the left side is doubling. I'm really upset and want to take it to the Mac store but we don't have AppleCare so I'm hoping I could atleast find out what's wrong?

I've got an old - 2 years - Maxtor 500GB USB external unit attached to my iMac running OSX 10.7.3 - which is used for backups. I received a couple of errors when copying some files so decided it would be best to erase it and start again with it. I used Disc Utility to erase it ( Mac OS Extended Journaled) but - and lord knows how I did this - its now telling me its got a capacity of 901 GB...
Info:
iBooks Author, Mac OS X (10.7.2)

My iMac seems to be a lot more noisier (a low humming noise, maybe the fans), than it was when I purchased it in a couple of months ago. When I first got it, it was the quietness and boot time which I was impressed with more than anything. Now it's noisier and boot times have doubled. I have noticed that the fans for for HD and CPU constantly spin at 1200rpm or more, with no applications open and as soon as I switch on my iMac.

I'll be ordering RAM from OWC for hex core 3.33 mac pro in the next few days. I can't spend $1k at once on 24GB, so I'm thinking of getting just 2x8GB for now and get the extra stick in about 2 months or so.
I know theres about 25% or so theoretical bandwidth loss with just two sticks, but what's the real, noticeable performance hit vs 3...if there is any?

After some difficulty upgrading my 4HD RAID0 2.66 MP to SL I've discovered my full screen Hulu and WB browser video is choppy if I use a full screen pop out window. If i go full screen it works fine. I've checked my Internet speed and it is as good as ever. I have not changed my config. of three LCD screens or any other hardware. This problem happens in both Safari and Firefox. I did have to reset the PRAM in order for the SL installer to see my RAID0 HD per Applecare. The bottom line is I used to be able to watch Hulu via a pop up expanded to the edges of my 24# LCD, and surf using one of my 22 inch screens. Now I can't unless I want the video and audio dialog to sych. I did confirm the the main Radeon 3870 card is still running at 16X. Could this be driver problems?

So I just installed the Apple ATI Radeon HD 4870 in my 2.66 quad Mac Pro1 1. Everything seems to be great but when I ran Cinebench I noticed that it is running OpenGL Engine, 2.0 ATI-1.5.48. In the results I see another 4870 with higher scores running OpenGL Engine, 2.1 ATI-1.6.6. My question is this. Is there something I should update for better performance? Is this a difference in cards, OS, drivers, firmware?

Well? Is there anyone using the 11.6" as the primary computer? If there is, post your thoughts here. Is the screen too small? How is the performance for your day to day tasks?

Has anyone tried running multiple virtual machines on these guys yet? I'm looking to run base installs of different OS's for my InfoSec classes. I'm really just testing different security configurations nothing fancy.
I'm looking at the 11.6/1.4/4gb of ram. Most of the time I'm only running 2 Virtual machines, just want to know if it can handle them.
I've seen some people have got win7 to run which is cool but the second os running is critical in this scenario.

Im thinking about buying a 13" mba to be my computer everywhere i go, but I have some doubts about it's performance because there are a lot of different opinions around the web.
It will not be my primary machine, since I have a sony vaio F (heaavyy for carryng around!) and a powerful desktop for gaming and rendering, but i will ocasionally need to do some work on adobe cs5, autocad, and google sketchup light work on the mba. Have you guys ever tried one of this programs? how is the performance?

I currently got the 5870 driving a 30" ACD and 23" ACD. Would there be any noticeable performance increase if I were get the gt120 to run the 23" and have 5870 run the 30" ACD (my work display)?

Anyone know if there exists a utility for 10.4 which replicates the "System Prefs.. Energy Saver.. Options.. Processor Performance" option but in a more accessible way? I tend to switch modes fairly often, so ideally I'd like a little menubar icon which I could click to toggle performance modes, or maybe a dock icon. No widgets please

My PowerBook 12" 1.5G has 100% CPU usage when playing back the new TV program from iTunes store. And sometimes it even choke.
While I have no virus scanning software, some programs running such as Opera, iTunes, Entourage and have about 20% CPU usage when idle.
Why is it so slow on a PowerBook while you can actually play that video on an iPod? Is it the iPod too powerful or it is just because apple did not optimize enough for older Macs (pushing people to new hardware)?
I have just ordered a new iMac but I am not happy about my PowerBook which is just one year old.

I just ordered a new Mac Pro 2.8 with the primary purpose of doing video editing on Final Cut. (5-45 min. videos here and there). Because of my budget, I cannot afford the the $800 price tag on the apple raid card but I would like to optimize my rendering and writing times. A lot of the forums I have read do not distinguish between software raid and hardware raid.
So here's my 2 questions.
1. Will I benefit from using the software raid in Disc Utility or would I be better off just using a separate scratch/write disc?
2. With such a fast processor and 3 gig Sata HDs, will raid 0 improve speed enough to make a significant performance jump anyway?
I would use a separate hd for my programs and regular files.

I have an original mac pro with the stock 250GB drive (along with 2 500GB and 1 TB).
The OS is on the stock drive. If I replace it with the 640GB WD Caviar (on sale at OWC for $80 - [URL] will I see much of a performance improvement?

I am sort of shocked how much low I/O performance mars overall responsiveness of my mp. Whenever I have some disk intensive app running the entire system begins to stall awfully up to the point when a simple task such as browsing becomes a painfully slow process. This situation is even aggravated when I concurrently access a flash drive. I have 4 Samsung 1 TB F1s and 8 GB RAM available. Would building a software raid 5 help to improve the situation? I reckon that transfer rates are part of a problem. Intels latest SSD Drives are also much faster than my F1s and also sport much better access times. Has anyone experimented with using such a drive as the system and application drive?

One of the stated features of 10.5.6 is improved performance of TC and TM. I've got a TC and have switched off TM b/c it worked so poorly on my Macbook Air. After about a week I would find that my TM would get stuck and corrupted and cause TM to stall on preparing and then fail to load the drive and then proceed to knock down the wireless network. Has anybody who was having problems with TC and TM in the past upgraded to 10.5.6 and seen improvements? I finally got my wireless network working alright and I'm not quite sure how convinced I am that TM will start working now.

I just noticed that Xbench gave me a better OpenGL score on my new late 2008 MacBook compared to 10.5.5, so I was wondering if anybody knows how much better the graphics performance actually is in 10.5.6? Although I just traded in my old white MacBook with a crappy intel graphics card for the new MacBook with a rockin' graphics card, I am curious how much the 10.5.6 update improves performance on the intel graphics cards. Can anybody compare the OpenGL results from 10.5.5 and 10.5.6 to see if I'm the only one who is seeing an improvement. Did Apple update the graphics card drivers or is there some other reason I'm seeing better performance?
