[R] --max-vsize and --max-nsize linux?

somtimes i have trivial recodings like this:

> dim(tt)
[1] 252382     98

system.time(for(i in 2:length(tt)){
              tt[,i][is.na(tt[,i])] <- 0
...and a win2000(XP2000+,1GB) machine makes it in several minutes, but
my linux notebook (XP2.6GHZ,512MB) don't get success after some hours.

I recognize that the cpu load is most time relative small, but  the hardisk 
have a lot of work.

Is this a problem of --max-vsize and --max-nsize and i should play with that, 
because i can't believe that the difference of RAM is the reason?

Have anybody experience what is an "optimal" setting with i.e.
512 MB  RAM in Linux?

Many thanks for help and comments
