How Much Does Internet Speed Affect Fusion--What Can I Do?

utekcnc — Sat, 24 Sep 2016 12:39:41 GMT

Good Morning,

How much does internet speed affect Fusion 360? I live in a rural area and my internet is 3.61 mb download this mornng and .81 mb upload. I just did a test. It seems like it takes a long time for Fusion to open and then to save parts and also delete parts. I have a couple questions:

1. I I would/could double or triple my internet speed will I see a noticeable difference?

2. What can I do until that happens? Are there any tips to using Fusion with slower internet speeds. I have went back to Geomagic some because of this, but I need the collaboration tools that Fusion has for many of my projects.

thanks!

You could work in offline mode and only go online once at the end of the day to let everything sync back to the cloud.

You must go online if you want to insert components from the browser.

Are you an AI Bot advertising for a web service?

Can you Attach a *.f3d file that you have created?

Do you have a link to a portfolio of your work?

First post to an ancient thread - looks suspicious to me.

Seems like the bots always pick up on ancient threads.

I am really tired of how slow and unstabile my Fusion 360 is especially on screen updates, selecting things with the moius for ex joints, or removing features that do not have history, assemblies and toolpath generation, and I cannot figure out what my bottle necks are, when ex. it takes at least 20-30 seconds to delete a bolt from an assembly til you can do the next thing.

Internet right now is as follows

Dell Laptop
Processor 11th Gen Intel(R) Core(TM) i7-1165G7 @ 2.80GHz 1.69 GHz
Installed RAM 16,0 GB (15,7 GB usable)
Storage 477 GB SSD KBG50ZNS512G NVMe KIOXIA 512GB
Graphics Card NVIDIA GeForce MX350 (2 GB), Intel(R) Iris(R) Xe Graphics (128 MB)
System Type 64-bit operating system, x64-based processor
Win10Pro

I need to buy something new to get Fusion to function acceptable, though I think a huge part of the issue is how Fusion stores data. When I open a large assembly (design mode) it seems like Fusion uses a huge amount of time loadíng CAM files, which really should not load unless you are in the manufacturing space of the specific part that you have tool paths for.

Where should I start spending money in order to get better performance?

This is a model of one of our machines (I cannot share file) is the heaviest we have, and after 3:28 minutes it starts loading CAM files) and it takes 13:10 minutes in total to open. With loading and update times of that magnitude it becomes both incredibly unstabile and unworkable. Massive gains should be possible, unless it is a FUSION/Server side issue, but I don't really know where to look.

While opening Fusion never used more than 35% of CPU as measured by TASK Manager, and of RAM Fusion used up to 6000MBS for the first 10-11 minutes and up to about 8000MBS for the last 2-3 minutes. Up till 10-11 minutes total RAM load was under 85%, but for the past 2-3 minutes it reached high 90'ties with other processes.

What would the most likely bottleneck be, and how do I best test?

Is it a good test to go somewhere with much faster internet speed and try to open this file again, or will it be undermined by cashed files?
