Hi. Last week I updated from 32 bit etch to 32 bit lenny on an AMD SMP
machine. I first cloned the system disk to an identical drive, and
updated the cloned drive. I still have the etch install untouched on
the previous drive, which has allowed me to do some testing. After the
update R has slowed down significantly. A user brought this to my
attention, and at this point we have only tested one script (multiple
times, different days).
Update: We just tried something a little different. My colleague's
script writes output to the screen. I suggested writing to pdf files
instead and it ran much faster; comparable to the speeds on etch. So at
this point I'm guessing this is not a R issue per se, but an issue with
graphics.
