EPDM Check-in slow (1 GB line) what can cause this? (network utilization rate on check-in 0.50% however 'Getting latest files is fast' 50% network utilization

I heard this could be a bad port on a switch..... what's strange to me, when getting latest files....large files (our download speed is 50% of 1 GB)

However the complete opposite on checking in files to the vault for first time the (upload speed is 0.50%) max

large company database and archive server are near by.....

2017 Sp4.1 both SolidWorks and EPDM

Any one else notice this or know what we should be doing to narrow down why check in times and timeout occur when we check in 100 files or more throughout the day.
