What is my bottleneck?

I'm currently running a Dell Precisioon m67000, with a nvidia quattro 4000m, i7 processor,16gb ram etc.

My problem is that when i work with some huge assemblies, roughly 2gb my computer chokes, either not responding or just using ages just to go between sub assemblies.Which is essential for me to do.

Would a regular workstation work better for me?

Appricate some suggestions on what i should get.

Are you running out of RAM? I use task manager to see if my physical memory is getting close to my memory limit. Everyone's definition of "large assembly" is different. If i am running out of RAM, I figure it's a large assy for me.

Are you using simplified representations to manage your large assemblies? In my work, we absolutely require simplified representations. It either takes too long to work on the master rep or sometimes the models won't even open (usually associated to problem models but sometimes related to RAM).

You might try looking at your config.pro options. There are so many possibilities that effect performance that I don't even know where to begin on that.

Your computer specs seems like you have a pretty good setup.We have laptop workstations that perform just as good as our desktop workstations.

I have a similar setup and it is simply slow due to the single processor nature of Creo. If I'm not mistaken, you have a 2.4ghz processor or something close to that. It is simply slow if its not multithreaded.

I have run into extremely poor performance in the past. If you set the graphics quality setting too high, your performance can go down hill exponentially. Turning off textures and setting the graphics quality settings lower in config go a long way to making the system remain interactive.

One last thing is to save your parts using the wireframe option. This can reduce file size significantly and help the file read time: save_model_display wireframe

Thank you both for quick replies. I'll look in to it more tomorrow.It's actually a 2,7 ghz i7.I also think it might be the ram. The assembly i was working with today went fine, but yesterday i worked with a 1.8gb assembly and it crashed very often after 4 hrs of work.

Also look in My Computer for the exact model number of your i7 - it should say something like "i7 3840QM".

http://www.cpubenchmark.net/singleThread.html shows the fastest i7 to be 2.75 times as fast as the slowest, so it makes a difference.

However, from your description of sudden 'chokes' I suspect memory is the most likely issue, or possibly a 32bit limitation as Doug says.

Are you running 32bit or 64bit version of Windows? The 32bit will only allow a bit over 2GB of RAM per process.

Most newer workstations should be 64bit and there aren't separate installers for 32 and 64bit Creo, I don't believe. That was the case with older versions, maybe WF5 / Creo Elements Pro 5.0.

Thanks for al the answers, it seems like it a combination of the memory and the cpu. Did abit of testing today.

Its a 64bit version fyi.
