Using R 2.10 on Windows: I have a filtered database of 650k event observations in a data frame with 20+ variables. I'd like to be able to quickly generate estimate and plot survival curves. However the survfit and cph() functions are extremely slow. As an example: I tried results.cox<-coxph(Surv(duration, success) ~ start_time + factor1+ factor2...

...time and not very successful in getting good performance out of our test set-up, I'm finally getting to the list with questions. Right now, we are operating a web server serving out 4MB files for a distributed computing project. Data is requested from all over the world at a rate of about 650k to 800k downloads a day. Each data file is usually only ever read 2-3 times and after some time deleted again. Thus typical data rates are about 30MB/s day in and out with a constant influx of new data at about have that rate. Also, file deletion is an ever ongoing process. Currently, this mach...
