Hi all



I'm looking at optimising my code and read somewhere that what I am doing 

is slow. My code currently does



<% 

' do some server processing

%>

html tags

<%

' more server processing

%>



and so on.



The post I saw previously said to leave code inside <% %> as much as 

possible and use response.write. 



I understand the difference between server and client side (!?!) but what 

sort of hit am I looking at by swapping in and out of <%%>. I thought that 

html stuff gets rendered at the same time so there is no hit.



Any comments gratefully received



Regards

Graham

It's called context switching, and it's a hit because two different

processes are used when the page is interpreted -- one for ASP and one for

HTML.  Switching back and forth between them during the interpretation of

the page slows things down.  Don't worry about it TOO much -- it's really

only a major bottleneck if you do it in a big loop.  Otherwise you're

looking at <1% gains in performance.



However, it IS a good idea to try and keep all of your ASP code in once

section of the page, to avoid spaghetti code and make it easier to break the

code up into functions, COM objects, or .NET code in the future.
