Hi All, I have a M/R script I tried to optimize the script as much as I can. I was just wondering if the yield and buffer field help for better performance in any way ?

@samyt I would like to know this as well. Please let me know if you find something or someone replies with a good answer. Thanks in advance!

As far as I know, M/R automatically uses yield when needed. It is used more for scheduled scripts

@rant I do know that yielding is not required in M/R. But I was wondering was how to speed up my M/R script further. If yield(any way of reducing this) and buffer could help, why not use them.
