can we do as many as we want to or any limitations ?

You can do as many as you want but you're governed by the # of connections to your account. For example, even if you had 20 of them, your account many only allow 10 connections so its pointless.

Totally agree what I was I assuming. Thank you! We should just make sure, math with concurrency connections

yeah I mean depending on what it does, I don't know why you'd need more than 1 deployment of a RESTlet. I can't say i've had to do more than 1 at least. Other things like scheduled/map-reduce you typically have more than 1 depending on the scheduling.

I just figured it out when you send request to restlet, it certainly taking time process and sub-sequent requests falling into queue to process, it is processing synchronously

restlets are basically servlets, you get a thread for each request

Don't know but it was just processing one request at time

are you sure you were making them simultaneously

Your right it was internal system that wasn't able to send at time
