[R] Improve performance of RConnection and Rserve

[Ranjana Girish]

Hi all,

If we execute an R script directly in R prompt in Linux environment, it
takes around 30 mins to complete.

The same R script if we execute from java using RConnection, eval and
Rserve for each line it takes thrice the time.

Basically the performance is very bad. And in most of the occasion it never
ends up in result.

Can anyone please tell how to improve the performance using Rconnection.

Thanks in advance

Ranjana
