[R] R 1.4.0 much slower than R 1.3.1

[Robin Hankin]

Dear R-ers

I've recently upgraded to R-1.4 but I have noticed that it is slower
to load datasets than R-1.3.1:

R-1.3.1:

> system.time(a <- read.table("~/people/academics/mitchell/nzsl02.27",header=T))
[1] 40.86  0.51 54.10  0.00  0.00
> 


R-1.4.0:
> system.time(a <- read.table("~/people/academics/mitchell/nzsl02.27",header=T))
[1] 293.24  30.76 478.35   0.00   0.00


The dataset in question is big ( 75306 x 27) but not desperately so.
Am I doing something stupid here?
