Hi All. I'm building an integration to NetSuite and the requirement is that, we want to set the timesheets and line items in NetSuite using REST web service. Currently we have Restlets but that's consuming a lot of computational resources on NS. Is this way feasible or are there any other/ better way to achieve this? any help is much appreciated.

RESTlets should just collect the information from the external application and then offload the processing to a map/reduce script or suitelet.

@Eric B Suitelet? Isn't that still going to be synchronous execution in the RESTlet?

Yes, I usually have a Suitelet that does nothing but execute map/reduce or scheduled scripts so eventually it's those scripts that deal with the data.

Do I understand you correctly that you have RESTlet -> Suitelet -> MR/Scheduled script?
