Update Data by Async Updates or Mass Update

Hi Everyone,

I need to sync the products included in a quote made in an internal system of the company with the Sugar's Quotes module, sometimes a quote includes more than 20 products.

I noticed that when I do a Mass Update via REST API is too much slower than do it by an Async task made with Node JS Request, for example, a Mass Update of 20 registers lates between190 to 310 seconds to be completed and it just takes between 700 to 1000ms, the problem is that I can't do more than 20 async requests until the API stop to process.

Someone else has a similar case than me?

How it was solved?
