Hi,
I'm preparing the migration of some classic ASP sites from IIS 8.5 (Windows 2012) to IIS 10.0. Currently I'm using Windows 10 as my "test" platform. The sites run fine and fast except for certain pages that take significantly more time to complete, like more than 10 seconds compared to less than 1 second when requested on IIS 8.5. The sites hit a SQL Server database and use a 32-bit COM object but neither seem to be causing the issue as many "fast" pages use both and when troubleshooting the "slow" pages the SQL queries run fast. I've installed failed-request tracing and nothing jumps out other than that some ASP statements seem to take a lot of time. One in particular jumps out, the Eval() function, but it works fine, just seems slow.
Does anyone else have these issues? Any ideas?
