ASA 5525X Slow internet

Dear All,

I have some issue with our ASA 5525X. Users are experiencing slow Upload and Download Speed and the Speed test also showing very less speed. I haven't done any recent change in the network. We have 500 Mbps ADSL Line. As i am new to ASA any help in this regard will be highly appreciated

Has the network always been slow or is this a new development? Do you know if you are using Firepower?

Have you tested without ASA bypass your FW ( connecting Device to directly to DSL?)

check Interface negotiation with DSL router?

Do you see any errors on the connected interface to DSL?

is the ASA connected to Lan side any switch? can you post the information about the switch?

Connecting PC directly to DSL Modem will give the output what is the ISP bandwidth you getting as you mentioned 500MB?

Post both inside and outside interface information output., if this connected to switch, post switch port configuration also.
