New ASA 5515-X Causing Slowness Between Networks?

We have a lab network (x.x.x.x) that is segregated from our corp network (y.y.y.y) by an ASA 5515-X.  When doing file transfers (anywhere from 80 to 400MB) from x.x.x.x to a server on the y.y.y.y network, it takes a very long time; upwards of 8-9 minutes sometimes.  The path flows as follows:

Server on y.y.y.y network > 3850 stack > 5515-X > 3850 stack > server on x.x.x.x network.

I am wondering if the inspect rules might be causing this.  Nothing in the logs; but packet captures on the ASA show packet retransmits.  Also, ping times are < 2ms and no missed pings.

Hi,As you would agree , this

Hi,

As you would agree , this would be a long shot but these are some things which you should check:-

1) Check for Interface Errors on the ASA device

2) Do you have any additional Module enabled on the ASA device ?

3) Are there any inspections for this specific traffic on the ASA device ?

4) Try the TCP state Bypass to isolate the ASA TCP state checks causing the issue

Thanks and Regards,

I think there is no interface

I think there is no interface errors because no missed pings

share your config

 

or try to switch off inspection rules

Here is the current config.
