We need help with a lightning component more from a design/architecture standpoint. 

We have a custom lightning component that is going to send attachments to a microservice.  Originally we did this via apex, however, we ran into size limits.  And we were told we could not increase the heap limits in Apex, so now we are doing this in javascript.  It works but it's very slow, takes 2-3 minutes for saving. 

We had support look at our code and they told us not to use javascript but to use apex, we can't do that because of what I posted above. 

We are really stuck with this and we have to have the attachments passing to the microservice we cannot not have this requirement. 

Any ideas on how we can solve for this. 

@Greg Rewis @Andrew Cafourek Can I cash in my phone a friend or go into debt if I don't have any.  We could really use some help.

The case we have open is 20887493.
