• Re: Ajax is very slow in Production Server

  I have the same issue here. Ajax in .net runs very very slow. The setting in web.config < compilation debug= "false" > < system.web.extensions > < scripting > < scriptResourceHandler enableCompression= "true" enableCaching= "true" /> </ scripting > </ system.web.extensions > does no help at all. Any other suggestion to resolve this issue?
