So I joined the server 'DayZ SWE 1-3 (Stress test)' shortly after the announcement of 'Stress Test #11' and spawned at Kamyshovo. This was on May 18 at around 16.30 CEST.

I went inside the the police station in Kamyshovo and found approximately 2 Scorpion SMG's, 3-4 Scorpion Mags and 1 MP5. Later I came to the police station in Staroye where I found several guns and mags as well.

The buildings seemed not to be looted before I came there.

Haven't tried to reproduce because this is probably tied to the amount of loot spawned at server start.
