IOread: ~1500 bytes/sec

[MikeHalloran]

... is about what SW2009.4.1 is managing to do, while doing automatic repair of a fairly complex object imported from a step file.

It's using exactly 50 pct of a dual-core CPU, and is using 0.5Gb of 2Gb that should be available to it under XP.

The file is actually on a Passport drive with a USB(2) connection that's pretty speedy. The drive light flickers once in a while. The computer's hard drive light is not flickering.

The IOwrite is not changing. SW is not updating the screen.
Task Manager says it's 'not responding', but I know from experience that, someday, it will finish whatever it's doing, and report success or failure. But it's only been cranking for an hour or so.

The Nvidia FX4500 has the latest driver, which only glitches when SW is using more than 2Gb of memory.

To me, 1500 bytes/sec just seems rather slow. It's not hitting the disks, so ... what do you suppose it's actually doing?

If I knew that, maybe I could figure out how to make it do, whatever, faster.


Thanks.

Mike,

50% of a dual core is what you would get with almost any CAD system. If you had a quad core you would get 25%. SWX is not multi-threaded so it cannot directly benefit from multiple cores. Multi-cores do help by letting SWX have one all to itself and the other cores do the rest of whatever operations are going on.

I'm not an IT guy, but I always understood it is not a good practice to access large files directly from a USB drive. You'd be much better off copying the files to your hard drive and then when the job is finished copying them back to your thumb drive.

Actually, that type of operation is one of the reasons why PDM systems are good to use. They copy the files across the network onto your local hard drive where you have the fastest and most secure access, then they write the files back to the vault on the network when you check them back in.

To your particular problem I'd suggest you try copying to your hard drive and see how that works.

Understood about the multi-core.

My computer came back from the automatic repair with >3000 gaps and a couple hundred bad faces.

It didn't refresh the whole screen, which had been blacked out by a screen saver; just the new portions.

So I set it to work on just the first bad face.

The computer's hard drive light is blackfront, only visible when it's on and only when looking perpendicular to it. The USB drive's light is much more easily visible.
I've tried it both ways; it hardly matters.
Disk access is clearly not the limiting factor here.
