Why is my drawing so slow between tabs?

[sneenanKFX38]

First time posting here, I don't know where else to turn. I've been looking for the last several days and working on this drawing way longer than I should have had to. I have no idea what is slowing it down so much. I've run audit, purge, deleted excess blocks, changed my layout regen options to cache model tab & all layouts, checked the z axis for any oddities, changed my MAXACTVP to 10, UPDATETHUMBNAIL to 0 and I am lost. It is a relatively large file at 17MB but I've run large files before with little issue. I usually work off of a local network but I've copied the file to work locally and am still having issues. I'm working on a Dell laptop with 32.0 GB of RAM and an i7-9750H processor. Any help is greatly appreciated. Thank you!

This is also quite the over-busy DWG file my friend, and all of your titleblocks are individual unique floating components,  not sure you are going to be able to speed it up too much more

Yes, unfortunately. I thought I ran the audit and purge already, perhaps it was a different copy of the file. What is that proxy list? I saw something in another thread from a few years ago mentioning proxies but I didn't see anything when I ran the proxy notice command. I am in the process of optimizing our layouts and our title block is one thing I intend to work on. Do you have any recommendations for the title block issue?

If you have the time you can do so, but it is going to take amount of time.

Your one DWG file probably needs to be dozens or more DWG files instead. Reference what you need in a ready-for-plotting only top file for print-needs (where your 30+ layouts will also reside). Again, many DWG files that you design and draft in, one DWG file for layouts and plotting only (with one or more titleblocks as separate DWG files that are only XREFfed into this one file).

I did not have access to the missing XREF, so it might have issues that need resolving too.

your file contained "proxies", aka object types you cannot edit or do much else with except look at, from other CAD programs and AutoCAD variants. I just got rid of them for you using a free safe tool called ZOMBIEKILLER (grab it from the Autodesk App Store).

Thank you so much! I didn't think to use several separate files as the modeling space and one ready-to-plot file as the final layout. I realize it'll be some time and I'll probably just trudge through what I'm doing now bc I have to get this finished, but I'll be certain to set something up for future use. Please excuse my clumsy posting format, I'm still learning this forum and how to navigate properly haha.
