OK... so IQ doesn't recognize the 128g for -iqlm, -iqmc and -iqtc, they have to be in MB. That's pretty stupid, it recognizes these for the -c option. Grr.
The following works and I see it is allocating 256GB RAM to IQ. Curiously, that wasn't improving performance, and I noticed the loader was I/O bound at 140 seconds.
So I moved the IQ files onto SSD. That made it slower, at 160 seconds. Now I'm really confused :-)
