We have 2 Mac G5s- bought at same time and are identical in all respects. When we get a PDF from a customer that Acrobat won't handle, we tiff it in Photoshop. One Mac rips thru them and the other grinds away. Fast one is about 4 times as fast as the slow one. I checked the Preferences\Memory and all are the same. Where else could I check to see if Photoshop, Mac settings that would affect speed are the same? I've checked all of the ones I can think of and can find no differences.

We have always had to use Photoshop on the CMYK PDF files from this customer. We use Macs, Quark and he was using PC, Pagemaker. Total knowledge miss match. It has always been easier to just tiff the damn things and has worked fine. We set at 710 dpi to ensure no jagged type, etc. when we go to film. We time the job to go to our imagesetter during lunch between newspaper output. In the past we used an older version 4.0 of Acrobat on an old 8500 to handle the bw files and output EPSes. Last month we had to tiff the bw files in Photoshop, because even the Acrobat 6.0.2 on the G5s gave an "unexpected end of file" message in the print manager when we went to film. We'll probably budget for Acrobat 7.0 (a couple of months before they bring out 8.0) but even if we do, we'll still have this issue with the 2 Macs rasterizing at grossly different speeds. (I even swapped memory, no help). We can get around the problem, but it's driving me nuts. |

Is there anything going on in the background? Is the slow machine used for Internet stuff and could have gotten infected with spyware or a virus? Have you tried repairing disk permissions and then running a program like MacJanitor to do the daily/weekly/monthly maintenance? I assume both have the same version of Photoshop ... right? Scratch disks set to Startup? Same setting for RAM % usage? Annnnd... I'm spent. If it's more than this stuff it's outside my knowledge range. I can't think of anything else right now. |
| Thanks, Macman, couple of those I can check. I usually ensure no programs not in use are turned off. I'll check on a couple of your suggestions. Machines are less than 2 years old and the slow one works fine in all other aspects. Probably crashes the least of any in the building. I'll look into your suggestions and get back. Thanks for the help. |
np, Let us know how it goes! |
Almost forgot. The customer I mentioned converted to Macs a few months ago and bought a disk utility- Tech Tools IIRC. When he migrated past 10.3.9 he ran the program and got a "some files have bad structures- fix?" message. Big mistake. He had to reformat his drives. As the guy on Hill Street Blues used to say, "Be careful out there."
