Performance Update

Day 2 of Rain: got wet going to the bus stop. Sunny on the way back.

Day 2 of Rain: got wet going to the bus stop. Sunny on the way back.

Today Apple released Performance Update 1.0 for a swath of recently made computer. Mine was one of them. Hopefully this update will fix the problems I have been having and trying to fix. After twenty minutes everything seems to be running better. Though it might be a placebo effect.

The update notes state that the issue was related to the hard drive which would explain why I had more hang ups while having Matlab process and save a bunch of data.

The forecast for the next seven days: rain.

The forecast for the next seven days: rain.

Within the first week of release I have been running OS 10.6 on my MacBook Pro and all was well.

Recently I noticed that I have been running on the integrated graphics card since moving to Seattle, this explained why it felt as if the system was sluggish. Once I switched over to the dedicated graphics card (NVidia GeForce 9600M GT) everything started moving faster. Almost everything.

Once an hour, once every twenty minutes or once every day the system would hang. For twenty seconds the system was not responsive, I could get in maybe two clicks before everything stopped. It was not lag as keystroked and mouseclicks made during this hang time were not registered in any way. The system just stopped. I have read about this on forums with one solution being to downgrade the EFI firmware from 1.7 to 1.6. This sounds risky since my computer shipped with 1.7 so 1.6 might just fail completely.

Sunday I decided to try to fix it on my own. First thing I did was verify the main hard drive and repair permissions. No major problems with either of these. Next was a hardware test off the original install discs, passed with no issues. The last hardware maneuver was to rest the PRAM. Back into running the OS I checked all the third party programs that run in the background. I found out that the major three that I use were out of date and lacking 10.6 support (Caffeine, Quicksilver and Keyremap4Macbook).

After these steps I have not had a hang in over a day. Usually I get a couple with Matlab running and I had it open most of the day. Hopefully this is a working solution else I will need to wait until 10.6.2 is released in the next month or so.

Uptime

This is the best uptime I have seen of any computer I have accessed.

This is the best uptime I have seen of any computer I have accessed.

The best uptime I have personal achieved was on my old Powerbook G4 with an uptime of 100 days when running 10.4. I have yet to be able to come anywhere near matching that uptime with either 10.5 or 10.6 (which has not broken ten days). Since I can now dual boot into Windows I will probably not be able to achieve a high uptime on my laptop. Even without the Windows partition I still have some issues to work out before I get it to be super stable.

The pictured uptime is from a computer in my lab, I just happened to check out uptime yesterday when it hit 500 days up. This particular one has a UPS and its own generator, it’s internet connection is also on a generator and UPS, so long as Seattle as a whole does not go on it will keep on going.

As for my laptop a few issues persist through 10.6. When I am running on my dedicated graphics card (instead of the integrated one) the system hangs for around twenty seconds every hour or so (so being ± 40 minutes). I think this is related to the 1.7 firmware update but I don’t know how comfortable I would be in downgrading the firmware. Especially since I think this computer shipped with 1.7 on it. The system also occasionally starts acting really weird requiring a logout. The last issue is that when I wake it from sleep some windows are blacked out for up to ten seconds before refreshing back to normal.

I might just need to do an erase and install with 10.6 instead of my current upgraded install. I don’t because my Microsoft Office and CS4 disks are in California while I am not. Add to those reinstalling Matlab (and Mathematica) and it is enough of a deterrent to reinstalling the OS, though I really should.
