Anyway, last week, when the developer offered it, I flashed my Samaung Galaxy tab over to an AGNi custom kernel that supports f2fs. The dev was also thoughtful to offer some custom f2fs format tools for the Tab 2 and a custom TWRP for f2fs.
I did a backup, took a deep breath, and formatted /data and /cache to f2fs.
WOW! The Tab doesn't benchmark any faster, but it is noticeably faster in use. No more lags in Boat browser.
I'm looking forward to the Cyanomod team offering f2fs for CM11.
