We use a 2Mb network to access ArcMap 10.2.2 to ArcSDE on SqlServer with direct connect.
In the simulation we set our office network to this bound rate. The performance was reasonable, about 3-4 second to open the onnection, same to load a layer.
Pan/zoom was slow but not too much.
We check the simulation bound rate with transferring files and it was really 2Mb.
Then we have a cellular network (with net stick). It gives us the SAME bound rate (transfer a file takes the same.
Open Studio management on the client that connects the database is a little slow but not too much.
Opening a connection to the database takes 40 seconds. Load a layer about 35-40 seconds too and pan/zoom is almost impossible.
It has the same bound rate and other clients (file transfer, studio) works the same as the simulation.
Anybody have an idea why?
