Inventor 2019 runs slow. Hard drive and GPU questions

[Anonymous]

Hello,

I'm working with Inventor 2019.

2 operations are running extra slow: 

1. Loading a large file from our remote server

2. Doing any small change to the model

I've tried to check the system performance while doing it and it seems that the hard drive always reach max. capacity.

Also my Graphic Card is NVIDIA K2000 which is below what's recommended. (only 2GB CPU)

My questions are:

1. Will a better Graphic Card (NVIDIA p2000 for example) help?

2. Will a better hard drive (SSD) help?

are there other factors I might miss?

The CPU is i7 3.6 GHz and there is plenty of RAM and Storage.

I've attached a video of the Task Manager while doing some stuff (zoom in and out and trying to move a piece)

Welcome to the Autodesk User's Community..

Operating System?

What updates have you applied to Inventor 2019?

What is the date of your video driver (through device manager)?

How much RAM do you have?

Also you sounds like you are working across a network..  Where is this remote server located?   If working across a network, that will be your weak point.   What happens (for a test), if you copy your files locally and see if that makes a difference?

RAM would be an important consideration: 16GB minimal, 32+ GB for larger models

Storage format is important: Are you using an SSD? (Preferrably NVME)

As for GPU: Inventor doesn't really hit the GPU that much in the processing part but Inventor does like using VRAM, around 4GB min, 6 to 8GB is plenty in most cases. I have an RTX 2070 which is barely touched apart from the VRAM.

CPU: 3.6gHz is good enough, anything above 3.5gHz is recommended.

As for Networking: How fast is your Network Connection (NOT INTERNET)

How far is the remote server from your workstation?

Thanks for the details!

We are using a local server to load the heavy models. (the server is besides me and I can control it)

The connection is wired and is 1Gbps. I can confirm files transfer by FTP that fast.

However, when loading the models using inventor, I see the network reaches maybe 70-100Mbps, which is much slower than the potential. The guys at the support couldnt tell me why

Any idea?

[leowarren34]

That's probably a limitation of your storage media,

What are you storing on?

If you can store on NVME (Type of SSD) then you can easily saturate 1 gbps, it's more costly but is definitely worth it for current projects.

I know recently Facebook was selling off Intel Data centre grade (I don't know the SKU name) 4TB NVME SSD off at around $350 (In Warranty) as they were upgrading to Optane.

Hi! Just based on the behaviors you describe, it sounds like there could be network security settings throttling the file transfer. Try this simple test. Copy the files from the server and paste them locally. Are you seeing faster transferring speed? BTW, Inventor does not dictate how the files are transferred via the network or copied over the network.

Many thanks!

I have some more questions for you.

Is the speed issue related to all data-sets or one specific model?

Does the model open without issues or do you get any missing files or broken link dialogue boxes?

Are you a single user?

Are you using Vault?

I would look at the project file to ensure all paths / library search paths are correctly mapped before contemplating hardware changes.....

In inventor have you unchecked the "Enable relationship redundancy analysis" setting in application options?

Running on network will slow everything down.

1G bits/s = 1000000000 bits/s = 125MByte/s

SATA hard drive run at 1.5Gbits/s.

SATA II from 3 Gbits/s to 6 Gbits/s.

SATA SSD max out around 550MByte/s due to overhead.

You'll get more overhead on network, so you'll never see 125Mbyte/s.

Fastest I get is around 11MByte/s copying GByte file.

Copying smaller files will be much slower.

Also network will drop packet when too busy.  You'll need to wait a few seconds to recover.

Another thing is anti-virus.

The server will scan the file when you access it.

You computer need to scan it again when it receive it.

Windows network is not efficient for file sharing at realtime.

Some will say media server work great.  Yea, because it don't care if a few packets was dropped.  Most likely viewer won't notice the missing pixels.

Can't do that on a CAD file.
