Hello Community,
i'm having a Connectivity issue, I've noticed that mismatch duplex:
ASA5525# sh int g0/0
Interface GigabitEthernet0/0 "outside", is up, line protocol is up
Hardware is i82574L rev00, BW 1000 Mbps, DLY 10 usec
Auto-Duplex(Half-duplex), Auto-Speed(100 Mbps)
Input flow control is unsupported, output flow control is ofF

Could this be the reason for the slow internet, or is there another problem like Cabling
Thank you

Port has speed and duplex hard-coded.

Yes it reason of low connectivity,
you see many late collision error this happened when half duplex.
just config duplex and speed manually.

Advise to setup both the side Full duplex and reset the counter and observe
