Hi --
See here:
http://www.freelists.org/post/linux-cirrus/26-performance-loss-on-TS7250-vs-24
But! Note at the time of that post, I was chasing a performance problem with
2.6 kernels that turned out to be the processor was running half-speed.
(That's the origin of the 'nFast bit' patch ...). So when reading the post
above, you need to *double* the performance of the 2.6 OABI and EABI. Not sure
I ever re-did the benchmarks with the CPU running full-speed.

Gnuplot can be very FP intensive, IIRC, so I'm sure you would approach the
18-20X speed up for EABI FP performance. I'd guess your runs would be under a
second, but it depends on what you have gnuplot doing.
