So i'm playing around with an idea.. and measuring some performance.... I have 2 handler factories, and one handler defined. first hanlder factory simply returns: return PageParser.GetCompiledPageInstance(url, pathTranslated, context); second handler factory returns return new IndexPage(); third is a straight handler, and it just context.Response.Write("Hello"); setting IsReusable to true or false has no affect on the performance, I'm not really interested in that. My interest is in the handlerfactories.... returning a new instance of a class that inherits from System.Web.UI.Page, is 3 times slower than returning PageParser.GetCompiledPageInstance.... Why? What magic does it perform to get 3 times more speed... It compiles it, yeah, but my page objects are compiled too... How how how?!
