I have a DT Pro database that is around 2.4GB in size, with 1407 PDFs and ~ 650 HTML files. Word count is 560,282 unique, 120,705,955 total. In recent days I’ve found that scrolling the treeview has become sluggish and spikes the CPU up to 90% (on one core). I’m running DT Pro 2.3 on a 17" Macbook Pro, i7 with 8GB RAM so it’s not the machine.
After much fiddling, rebuilding database, running “repair”, etc. I finally copied the database using Finder. When I opened the copied database in DT the problem was done. So, I moved the old database into a temp folder and renamed the copied database to the same name as the original. When I opened the “copied-and-renamed-back-to-original-name” database the scrolling problem was back. Closing DT, renaming the database to any other filename and then reopening “fixes” the scrolling problem.
So, it seems that there is some other (cached?) data stored somewhere that is messed up that might be causing this problem.
Does anyone know a solution to this?
Also, how large can a DT database scale to? Am I reaching some sort of limitation?
