connection speed to server

sergei_nesterov

I am in Russia. I'm studying Onshape, I'm making small details. With the number of features about 26 units, noticeable slowdowns appear in the program's operation. So the question arises, Onshape only works on one server? , can there be an option to choose a server? Is there any way to speed up the data processing?

Hi sergei_nesterov,

I would recommend going to the 'System check' page to get a quick assessment of your setup and connection.  As part of it, it will tell you which region you connect to.



For example, my check page:

This is my Test. How I can see my PC not have much power. Is the video card to blame? 
She is not young, but she copes with her duties. If I were drawing in an ordinary desktop-3d-application, then there would be no slowdowns.

What should be the characteristics (hardware) of the computer for comfortable work in onshape?

Hi @sergei_nesterov

It does appear that your graphics card is probably causing the issues you are seeing, the triangles and lines per second metrics are fairly low.  The connection to the server is responsible for delivering geometric data to you.  If you experience slow load times when adding, editing, and removing features, this could have to do with either a) your model's complexity or b) a slow connection to the server.  If you are experiencing slowness in framerates, selection, and other interactive performance after the changed geometry has loaded, your problem has to do with your graphics hardware.

We put together an official hardware guide here:

And some of our users have been discussing their own hardware and performance here:

It's pretty obvious the GFX card does affect it, but whether it affects the Onshape object computation/compilation speed, or just the image redraw speed, I'm not sure.

Hi @SledDriver

Your graphics hardware will affect interactive performance (rotation framerate, redraw for highlighting when you move your mouse over the geometry) and your CPU will affect geometry processing a.k.a. load times (both initially opening the document and upon feature creation, feature edit, etc.)

@sergei_nesterov - Your latency numbers look OK (and as expected from your location to our servers in Ireland). I think your GPU performance is definitely to blame.

What version of Ubuntu are you running? Which graphics drivers?

Yes. It looks like my problem.

 it's time to do an upgrade.

Another question, which browser is preferable?
I use Chromium Version 64.0.3282.167 as major browser for internet surfing. And Firefox 58.0.2 as spare browser with one opened tab.

john_rousseau

Both browsers are fine. At least on Mac, the latest Firefox is a little speedier, but Chrome is what I use on a daily basis. Either should be fine after your upgrade. The nice thing about Onshape is that you can easily test multiple browsers and see what works best for your environment.

Let us know what your experience is once you do the upgrade!

sergei_nesterov

Good day, all ! 
I did the upgrade. Now 3d is displayed smoothly (move, rotate, zoom, highlight elements). Thank you all for your prompt help!

Probably won't hurt to close some of those tabs either. You're just overloading that old dinosaur

This dinosaur is still capable of much! I had another 4 browser-windows open. The computer worked without complaints. The questions were only to 3d in the browser. After their closing, nothing has changed. By the way, in Firefox 3d was smoother.
