R slower after etch->lenny upgrade

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). etch -> 48 seconds lenny-> 4 min 5 sec I compiled a kernel on both etch and lenny to see if there was a comparable slow down. etch -> 45 min lenny -> 47 min 35 sec So, the kernel compile is a a little slower on lenny. During the upgrade there was an error of some sort about updating the following packages: r-base-core r-cran-kernsmooth r-cran-mgev r-cran-cluster I deleted those packages and continued with the upgrade. When the upgrade was finished, I reinstalled those packages. Other than that minor issue, the upgrade went really smooth. Cheers, Gary
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.
