Inventor Assemblies have become very slow

[travm]

Hi, I am using IV 11, with all the newest updates. I have an amd opteron 2.6ghz with 2gb of ram. 2 x 200gb hdd Raid-0. Windows XP.

basically constraint solving is very slow in the large assemblies, and dragging unconstrained parts or partially constrained parts so slow it is almost impossible.
Day to day this is killing me.
Any ideas on how to speed it up?
I have lots of work features in the assemblies,
thousands of constraints, and hundreds of parts.
Supressing parts does not seem to improve the situation much.

Thanks
Travis

Are you running Win7 yet? Does your Raid Setup support TRIM? If no to these questions that may be your problem.

2G of RAM is not nearly enough for larger assemblies. (For reference many of us who just got new systems are going with a 64 bit OS and 12G of Ram.
You also didn't list your graphics card. So lets assume you have a 512M graphics card.. Now with your 2G of RAM you only have 1.5G left after taking the video ram into account. Then maybe the OS plus all your other open programs use another 1G..Now you have 1/2G left which can be eaten by Inventor in no time.

This is not true.  If a 32-bit OS (and we
don't even know if he IS running a 32-bit OS) could only address 2GB, then you
would be correct; however, a total of 4GB of virtual memory is addressable by
x86 architecture.

In any event, 2GB of physical memory is simply
not enough for anything other than small assemblies.  Personally, I
wouldn't want to touch Inventor if it was running on anything less than a 64-bit
OS with 8GB.

You mention assemblies. I hope you are using many, many subassemblies as
well. Is that correct?

unless I'm misunderstanding what you're saying, you seem to be combining virtual and physical memory.

I believe mcgyvr was talking about RAM only, not virtual memory.
IMO, anytime you're working in virtual memory, you're in trouble already, as it is 1000's of times slower than working in RAM.

Yes, Many sub assemblies. I have all hardware used in this assembly assembled into sub assemblies as well (bolt, washers, nut).
I have made many work features invisible which seems to improve things abit.

My video card is some form of Quadro FX 3400/4400, not sure about memory, again im thinking 512mb.

I have asked for another 2gb of ram, but the damn motherboard i have is a server board and requires specific registered ram modules that are a pain to find.

I think i'm stuck with this system as it sits for another 1-2 years.

So yeah, any advice on speeding it up, even marginally would be welcome.
Thanks

what about adaptive parts?
do you have them all turned off (not adaptive)
Are you using them intentionally, or are they just a result of projecting stuff from one part to another?

[travm]

Yeah all top level adaptive parts are off. and grounded where possible. I found early on that adaptive parts = nuke your work, if left unattended.
Some of the problems i think are redundant constraints and unnecessary work features.
I learned to use inventor building these assemblies and now that I know best practices and better ways to do it i can see the error in my ways, however cant exactly (yet) justify the time of reubilding the entire assemblies and all sub assemblies.
