File Downloads using Chrome are much slower than Microsoft Edge

asked 2019-06-21 21:22:41 +0000 gravatar image

My company is having an issue with file downloads from an internal website which has two IPs and using load balancing. Chrome goes much slower than Microsoft Edge. I'm new to using wireshark, and I'm doing captures while using both Chrome and Edge to download files at the same time, but how can I tell which traffic is related to Chrome or Edge in the capture? I need to do file downloads at the same time to see which target IP is the slow one, doing it one browser at a time doesnt give me the data I need. I have tried uninstalling and reinstalling chrome and edge and a complete OS installation. We have many systems with this issue on our network.

A display filter of

http.user_agent contains "string"

where "string" is something that {Chrome, Edge} puts into the User-Agent: string might allow you to identify HTTP requests from a particular browser; once you've found the request, Analyze > Conversation Filter > TCP should show you the entire TCP session in which that request was transmitted.

You might have to look at a session from Chrome or Edge to figure out what string to look for in User-Agent.

Thanks Mr. Harris! Excellent info, and it sort of worked. When I did a download using Chrome, it showed Chrome for the agent, but unfortunately, it also showed Chrome when I used Edge (windows 10). i thought I did something wrong, so I tried it again, same results. I then tried another system, and Chrome showed Chrome, but Edge showed multiple browser types, Mozilla, applewebkit, chrome, safari, edge (all on the same line) very strange. I'm going to keep poking, thanks again! gravatar image[email protected] ( 2019-06-24 15:23:33 +0000 )edit
