[R] Data Frame Search Slow

So, here is the result time from using the datatable package:

> user  system elapsed 
>   0.800   0.012   1.847

Here are the methods that I am using:

ush <- data.table(read.csv(...))
setkey(ush, product_id)
s1 <- subset(ush, product_id == product.id)

Seems like a minor improvement but not enough to get those subsets in less
than ~2 seconds.  Am I doing something wrong I wonder...
