I have two different views that makes upwards of 500 partial view calls each

  • 0

I have two different views that makes upwards of 500 partial view calls each to a common partial view. Good design tells me that I should leave the partial view where it is and reference it from both overlying views to prevent code duplication. Unfortunately, performance suffers – copy-pasting the partial view in each of the other two views yields a 300ms improvement.

Is there anyway that I can, include a partial view in an overlying view, reaping the performance benefits of not using the actual Partial() call, while at the same time not having to maintain duplicate code? Note – I realize that I could write some sort of VS add-on that would copy-paste the view code, but I am looking for other options…

    Things to try that might improve performance:

    • Use @{Html.RenderPartial("_foo");} instead of @Html.Partial("_foo") to include the partial
    • Always do your benchmarking in Release mode. Lots of optimizations and caching are performed by ASP.NET MVC in contrast to Debug mode.

    If the previous 2 suggestions didn’t yield the required performance then you might try replacing the partial with a custom HTML helper that will generate the HTML fragment. This could work if the HTML of the partial is not very complex.
