Everytime I "Export For Screens..." in PDF format it get's slower and slower

[Silas Yamakami]

Hello,

I use export for screens to export many artboards in PDF for simple vector artwork like brand assets (brand_with_tagline, horizontal_logo, vertical_logo, symbol, brand_blue, brand_yellow, etc.) everytime I need to export the same file multiple times for Pantone, CMYK and RGB versions of those same artboards, but every time I export, the time it takes increases. For example: one file with 80 artboards take 0:10s to save each artboard as a separte file in Ai format, but takes 2:00s to save in PDF for first batch, then 2:50s for second batch and gets slower and slower. The problem don't happens when I save in PNG or SVG formats and I need to restart the computer to fix it.

I use Win10 - 20H2, Illustrator 25.2.3 and I am saving the files in a fast M.2 drive, the PC, I believe, it's not the problem, it's a Ryzen 9 5900X with 32GB of RAM and my notebook (i7 9750H also with 32GB of RAM) have the same problem. Looking in the system monitor, it shows that the Illustrator only use one single core to save the files unfortunetly.

Is this a Win problem or a Illustrator one?

Do you save those files to the local harddrive?

Saving in the OS drive a M.2 SSD (XPG AGAMMIXS41-512G-C), but I just tried saving in the local HDD (Seagate ST2000DM008) and got the same problem, though the first save took 1:00s (faster than the SSD) but the second batch took 2:30s just changing the color mode from CMYK to RGB.

I would report this to  http://illustrator.uservoice.com

and see what the engineers respond.

I will try there.

Same here. When exporting multiple artboards one at the time it's almost in real time, when 2 or more artboards are selected start the pain. I tried with multiple pdf options (even custom by me) but nothing seem to change. It happens since 2021 (now i'm on 2023), but in the Beta version everything seems to be fine.
