Hello @NateNex, server resources usually includes more than a map, such as scripts and mods which can take up several hundreds megabytes of space.
Try clearing your MTA resources cache and join one of the servers you're having issues with. Your resources cache should now only have this server's resources and you'll be able to see how large it is. If it's only a few megabytes in size, then it's a connection issue you're having, as your download speed is roughly 1.8mb/s and should be able to download a few megabytes in no time.
Resources cache can be located in MTA SA\mods\deathmatch\resources
