Edit Question
Title
Body
I like using partials in my Razor views. It makes the code nice and clean. But is there any significant performance cost of using partials? I've created a simple test. It shows that using partials is much slower. test.cshtml: @{ var stopwatch = new System.Diagnostics.Stopwatch(); stopwatch.Start(); for(var i=0; i<1000; i++) { var str = "my string #" + i; @Html.Partial("_MyPartial",str) // replace with @str on second test <br /> } stopwatch.Stop(); <br /> @: Time elapsed (ms): @(stopwatch.ElapsedMilliseconds) } _MyPartial.cshtml: @Model The code with the partial executed in 340ms, while the inline @str code was showing 0 or 1 ms. It is really shocking for me because it means I should get rid of all my cute partials, at least of those in loops. If anyone wants to confirm or criticize my experiment, you are very welcome.
