Umbraco 7.3 on Azure Windows Server 2012 VM is Extremely Slow
Hi All
I've currently got a VM setup on Azure which hosts our Umbraco application. The application is medium to large in size. We're also running the database on the same server.
Basic Server Specs:
Processor: Xeon CPU E5-2673 v3 @2.40 GHz
RAM: 7GB
I'd assume these are perfectly fine specifications to run two IIS sites on (one is the live environment, the other is test).
When I deploy a new release through Octopus, it obviously has to rebuild all the indexes and temporary data. The problem is, mostly it is extremely slow to load, we're talking 3-4 minutes for the initial load, then for each request after that it takes about 2 minutes.
I've seen a lot to do with useTempStorage however Sync and LocalOnly have no avail.
What's worst is that the problem is inconsistent, sometimes the server speeds up and loads within milliseconds, but then it has its bad spells where it takes minutes.
I'm pretty sure it isn't the code, as to confuse matters we have another test environment on our local physical Windows 2012 server which runs (and always has) fine.

I'll post any updates.
Any help would be greatly appreciated.

This issue is resolved. I upgraded to Umbraco 7.5.11 and it has had no issues since.
