Jpeg file size is dramatically different in SF 8.8 (vs 8.5)

Hi, and thanks for a great tool!
I've upgraded to Silverfast AI 8.8 (on a Mac running Mavericks, connected to a Coolscan 9000) and noticed that my default 35mm slide scans were now 1.5Mb in size (JPG baseline), from around 10-15Mb with version 8.5.
Scanning slides (w/o iSRD) with the settings: 4000 dpi on the rainbow slider and a full active frame, yields the following results:
- same pixel dimensions (around 3500 x 2500)
- cannot tell if they are of different quality at first glance
- EXIF data show 40dpi vs. 600dpi
- file size of 1.5-1.8Mb (versus >10Mb)
I've played with all sorts of combinations (Custom presets, etc), but cannot figure out what -if anything- is wrong.
Just to be sure, I've downgraded to 8.5.
If you get a chance, I would appreciate some guidance on this issue.
Thanks in advance.
