AZURE DB: Why are queries running slowly on large tables?

Question

Microsoft Azure

Hello.
Has anyone encountered a database performance issue on AZURE.
My table has about 150 thousand records, on the local machine the simplest query
select * from pages as p
where p.host = 'test'
runs in 170 ms
, but on the host the exact same query to the exact same table runs in 3200 ms .e. almost 20 times slower
(Price category
S0 Standard (10 DTUs))
Maybe someone faced such a problem?
