I'm using Glimpse to debug some perfomance problems in my website, and it seems that the server/framework sits iddle for too long between method calls.
This picture shows 320 ms of server time;
This second picture reveals that 125.29 ms are used by ViewResult.ExecuteResult (I understand that as "rendering", which seems pretty slow to me, considering that my views are pre-compiled - more on that below);
But the really odd thing here is that more than 100 ms are pretty much wasted with iddle time, as you can verify in this picture.
Those little blocks representing server work sometimes account for 0 ms! But then there's a lapse of about 15 ms before the next block.
Is it really iddle time? Do you have any tips for where to look next, or how to optimize this?
Disclaimer: I've been looking into this for a week or so, and I have already found and applied those general performance recommendations, like:
- Only one View Engine is active (RazorViewEngine);
- Run in Release mode;
- Specify full view paths, like "~/Views/Folder/ActionName.cshtml".
Besides that, Donut Caching is active, views are pre-compiled with Razor Generator, and I'm using Glimpse for diagnostics. Anyways, I've tried disabling these things to ensure that they were not the offenders, and I verified that they're actually improving the times.
Thanks in advance.
