We have MSSQL, some C# web services, some ASP.NET, and some AJAX. We’re having terrible load times, normally 2-3 seconds to refresh a page, sometimes far more. I have no idea where to start.
What profiling tools are there, across the entire end-to-end, to identify where the biggest bottlenecks are?
Your best bet…as I’ve said a million times before…is the Red Gate set of tools.
ANTS Performance Profiler is the tool for you.
For SQL Profiling, you can always use the built in Profiler that comes with SQL Server.
