Folder Sharing Speed

I have a 900MB folder saved locally on my desktop (MAC). I have shared this folder with Jump Desktop so I can access the folder when working in a server session (PC). My problem: when I open my file explorer window in a server session, it takes way too long to load my shared folder. Sometimes I have to force quite and try again. Is this normal? Is my shared folder too big? When I turn file sharing off, the file explorer window in a server session works/loads perfectly (without sharing folder from desktop).
