We are working with a Ubuntu server and we use Samba as shared resources protocol and we have LAN. We think it is not a network problem or server or Samba because when we open big raster files (orthophotos from 300 mb and over) we have made some tests consuming this photos on the network using QGIS and the connection is really fast, like they were local files. When I try to connect to the share folder that have the raters ArcMap gets really slow just trying to connect to the shared folder with the data.
What could be the problem, how can I get if work faster? if anybody could help me I will appreciate that.
