Performance, General

[payingtoomuch]

Having long xref load times, long regen times (at times) and long publish times.

Note I have another thread that was started that kind of got convoluted so I'm abandoning it. Established that my  current system is pretty much fine and some drawing clean up I could do to correct any drawing issues. I've taken all that advice with some success but still having uncomfortable issues.

I was asked for this in other thread so here goes.....

My laptop is an ASUS ROG Zephyrus G14GA401 IV

I'd like to get to the bottom of some of this.

1. I ordered more ram. Currently have 16 gig. Replacing one 8 gig stick with a 32 gig stick hopefully early this week.

2. My laptop is capable of handling a total of "approved ram" of 32 gig.  For my setup I have one stick of 8 gig on board not accessible ram (soldered) and 1 stick 8gig in a slot that I can replace. Approved total ram is 32gig (8 gig soldered +24 gig stick. But, no such thing as a 24 gig stick so I had 2 options- Replace the 8 gig stick with either 16 or 32 gig stick. The 16gig stick approach is "approved" (Total 24gig) whereas the 32 gig (Total 40gig ram) on board ram will have some "issues", primarily related (and I'm not 100% clear on this) related to only a certain portion of the ram being utilized as dual channel. Otherwise the ram itself is identical. So, this leads to next question.

3. Does autocad take advantage of dual channels? Would it be using dual channels when I publish from within the drawing. Which leads me to my next question.

4. There are HUGE HUGE, I'll repeat HUGE performance differences when I publish from within these particular types of drawings vs when I "publish" through using the sheet set manager. If I shift select multiple tabs and publish it takes forever. If I publish by sheet set manager and select the sheet set folder itself, right click "Publish to PDF" it speeds things up tremendously. I can't for the life of me understand what the difference is. Anyone?

5. I mention 4 because I'm wondering if by not having dual channel ram, it will potentially affect either one of the scenarios..... publishing via sheet set manager vs publishing via layout tabs.

6. Here is a screenshot of my processes.

Memory being used is almost exclusively autocad. This varies and have seen it around 88% at times.... maybe higher

This screenshot is taken when I'm reloading an xref (just one selected for reloading.... not all)

7. I was (and still am) wondering if dropbox might be creating some of these issues. But, as you can see from the processes in the screenshot it doesn't appear to be affecting much. But maybe 170 meg is significant all things considered.

8. When I look at all the processes and my cpu usage never really going above 11% that would say to me that it's a non issue.

9. My GPU similar, never over 10% or so

So, only thing I can figure is that all this is either a ram related situation or a AutoCAD related issue.

Hopefully some of you will have thoughts on this.

one quick observation from reading your OP is that since you're accessing all your dwgs including xrefs via dropbox, the speed is vastly impacting by your internet bandwidth. Typically with this kind of cloud based storage it requires the files to be downloaded from the cloud into your local drive so that they can be worked on. The question then is will you encounter simliar issues when all the dwgs are stored on your local drive including your xrefs and then opened from there without dropbox?

I kind of tried to get to the bottom of that by copy pasting the files onto my computer.... thinking that would eliminate the connection to drop box. No performance benefits observed.

That being said, not sure what I actually accomplished by this copy pasting. So, I contacted drop box to see if I could get to the bottom of it. They responded via email but it was more or less a generic answer that was going to require some doing on my part to be able to address the question.

So, put that on the backburner and looked into other options, which, thinking additional ram might help so started down that path.... which led me to the post.

That being said, as mentioned in the post, it doesn't appear that drop box is using any memory (much/ relatively anyway) so thinking now it's not the culprit.

Hopefully some others will chime in. Would love to get to the bottom of some of this!

... also, your software is not fully updated, that needs to be your priority above all else

And this might not be helping you out either

Other things to try as well as disconnecting from your DROPBOX while you sort it all out:

and for PUBLISH https://www.autodesk.com/support/technical/article/caas/sfdcarticles/sfdcarticles/Publish-takes-a-lo... 

Your focus on RAM as the fix is not exceptionally relevant for the most part IMHO.
