YellovvYoshi - We definitely need to determine where the slowdown is occurring. It's most likely not related to RAM in any way. It's much more likely to be the speed at which MobileSheets can render the pages which can be a combination of GPU and CPU processing. If the PDF itself is poorly optimized, then following the instructions that Frank Cox provided could actually significantly help with the problems you are seeing. I have had PDFs users have sent me that took 6-10 seconds to load and after I rebuilt the file, it took a fraction of a second. How long is it taking for the first page of the file to render and show up when you first load it? If it's taking a full second or more, then there is probably a lot of room for improvement. I'm not sure if you are allowed to share the file you are using, but if you want to select it on the library screen, tap Share->Export as .msf and share the .msf with mike@zubersoft.com, I'd be happy to take a look at the performance on several of my devices to see if I also experience what you are seeing. If you can't share the file, then investigating this will become a little more difficult, so I would suggest starting with rebuilding the file if you can.
