LTM OneConnect Profile for short API http request

We have some client using

API

calls to our servers and they are short live request, these web servers are not browsable they just serve API.

We have notice request rate is very high which i am seeing 900 TLS almost and i have notice our Web (apache) getting timeout sometime because of very high connection rate on webserver on

netstat

i am seeing thousands of

TIME_WAIT

so definitely my server running out of resources even server CPU load is

1%

or

2%

We are thinking to use

OneConnect

Profile but not sure its going to benefit us or not and how? I read about OneConnect profile but i am little confused and need some advice how we should utilize it.

Question:

1. If we use OneConnect does that means it will open only few connection to server right?
2. We are using

   Auto Map

   SNAT so what will be impact on OneConnect Profile also we are using

   XFF

   feature to extract client IP.
3. What if we disable

   HTTP 1.1

   on apache webserver which will close connection faster in that case how does OneConnect profile behave?
4. for test i have enabled oneconnect profile on our Dev LTM and send some http request from multiple but i am seeing its opening individual connect to server and not bundle them in single connection (We are using Mask 0.0.0.0) is that how openconnect works?
