NAV 2016 + Azure SQL Database - performance

Hi Guys,

i have a problem with my NAV + Azure environment.

for my Australian Customer i've prepared Azure environment:

1. VM - D2_v2,
2. VM Region - North Europe (partner it's from Europe),
3. Azure SQL Datebase S0/S1,
4. NAV authentications : NavUserPassword

using NAV on a server, everything it's OK.

but using Windows Client from local computers my customer - NAV is very slow.

Customer has ethernet 10 Mbs .. i didn't try turn of antivirus.

so do you have some ideas about my problem, maybe do yo have some proposal about azure VM/SQL settings?

Best regards,
James
