Spent about 30 minutes creating a visual filter to highlight bits in BDB to make it easier to find various verbal forms, etc - nothing fancy, just matching Qal, Piel, etc. and applying a yellow glow. Anyway, after 30 mins or so Logos is up to 1.42GB (!) of RAM, as shown in the screenshot below.
Guess the dev team want to profile that code (and deal with the performance issues associated with creating / editing visual filters and highlighting styles - documented elsewhere)...
