Hi Guys

I have a site which is performing very slow when deployed on Azure. However, the same site's performance is very good when deployed on our own server. Can you please advise/guide on the possible reasons for this and the way to debug/fix the same.

Let me know if any more details are required from my end.

Thanks

Hi,
 Thanks for Posting.
  Have you deployed a website or Cloud Service ?
  You might find the Below threads and links useful to diagnose the performance issues.

Hi,

In addition, the initial request takes long, then that would be because you are hitting .NET apps cold start. Many .NET apps are slow to JIT and load all their .NET requirements, but once everything is loaded, they are fast.

I am having the same exact issue. Were you able to resolve it? It has nothing to do with how the site is deployed (cloud service in my case), the server load (2-5% CPU in my case), the query performance (even very simple pages take 5-10 seconds to open) or cold start (it never speeds up).

Microsoft asks the same questions and points to "best practices for performance", but this is only to distract from the actual issue with Azure itself. I blame it on the latency between cloud service and Azure SQL. And before anyone asks, yes both servers are in the same data center (West US) and no, there are no performance degradation alerts in that zone.
