Hi everyone!
I'm using R 2.0.1 for Mac OS X in a classroom with 40 eMacs running Mac OS
X version 10.3.6.
These Macs are network based, meaning that the students log in to an
XServe G4 where their user accounts and home directories are stored.
The problem that I'm having each time a group of students (usually 7 to
10) use R is that the whole system get incredibly slow.
The response time for opening an application while the students are
running R is around 5 minutes.
If a student wants to log into the system while others are running R, it
can take up to 10 minutes for the student to get logged in.
Everything gets very slow that it's almost impossible to work.
When I look at the server Graphs, the CPU usage of the first CPU is always
100% when these students are using R. The second CPU is left at 15%.
When these students quit R, then everything's is back to normal again. The
usage of both CPUs go back down to between 5-10%.
Is there anyone out there using R in a university like this?
Does anyone have an idea what this might depend one or maybe a solution?
I can provide some more information if anyone wants, if you think you can
help me.
Thanks in advance
/Sam
