For information, I converted one of them (decode-vaio.pl) to sysfs
today. Works great, and the driver optimization serves its purpose:
decode-vaio
2.4.24 : 0m1.990s
2.6.1 : 0m0.550s
2.6.1+patch : 0m0.440s
The benefit is less impressive because the script gathers more
information than "sensors" does, so it reads 6 out of the 8 slices
("sensors" needs only 2). The three other scripts should take more
benefit of the optimization (I'd expect a 4:1 speedup for
decode-dimms.pl for example).
Another thing I forgot to mention in my previous posts: the speed
improvement applies only to the first time you run sensors or the
scripts, or after 5 minutes have passed. Consecutive reads do not
refresh the data so the speedup doesn't apply here. Still I think it's
great because the first run is what most users will remember of,
especially if they find it slow ;) and the buffer wears of after 5
minutes anyway.
