Hi
I'm observing a huge difference in the performance speed of R on Windows and 
Unix, even though I know that my Unix machine is much more powerful than my 
Win machine. 
In particular, any character processing task is very time consuming on Unix.

strptime(x,"%H:%M:%S") is about 10 times slower on Unix for vector x of the 
length of ~ 500. read.table() also is very slow. is there any way to speed up 
these ?

Thanks a lot,
Vlad.
