Compare speed very slow when compare local foler with Shared folder in LAN

[swpatrick]

So I have 2 PC, the file/folder transfer speed(like copy and paste speed in file explorer) from LAN shared folder to Hard drive is about the same, but when I use WinMerge to compare two folders (one in hard drive, other in LAN shared folder) there is a huge speed difference, the fast one is like 20s and the slow one is about 400s, does anyone know what cause this issue? Thanks

Are they folders containing many subfolders that also contain many subfolders that will contain files? I ask because my network comparisons are super slow because of this. Gigs of small files in nested folders will take time.

What I would like is the ability to poll a folder locally, then export that result to a file that can be brought to the 2nd computer and compare against there, without needing to compare across the network.

yes, the folder structure is like what you said. I don't unserstand the second part of you answer.

Turn off yours AV software, the any LAN action will speed up.

well, both machines running the same AV software, if AV is the reason, why does it only slow down compare speed on 1 of the machine, anyway I will try to turn AV off to see does it make difference.
