I agree, server side caching can do wonders (especially usefull for public sites), but you have to carefully design your application with server-side caching in mind before you build it :)

Another great trick regarding client side caching and response-headers (that really makes a difference) is the one from Tomas Nielsen:

I've seen very few people leverage domino server side caching. It's an heritage of 4.61 evolution, has a lot of caveats (only for anonymous request, for certain domino urls etc...) but can be a real performance boost (by caching the generated HTML by domino, server side, for a defined period of time)

I've begged IBM to enhance it (so it may behave like Websphere dynacache in terms of flexibility but it never happened).

You could just claim that you sped up the postings and finished the week early. :-)

Re: hosting YUI libraries outside the NSF, for public internet applications you could just use the Yahoo! hosted versions. This was a relatively recent announcement over at the YUI blog: {Link}

and {Link}

They include version numbers in filepaths (a good idea for everyone's own libraries when doing the aggresive caching thing) so you can use the version you've developed/tested against on an ongoing basis.

Julien, you can still encode individual files yourself and create some web site rules to served those.

Alex, I think you might have ruined tomorrow's post. ;-)

In this iNotes tunning article {Link} we can see that enabling GZIP is not always a good choice and can be sometimes negative.

I'm not sure it's a really good option.

Good week Jake.

Speeding applications involves a lot of considerations, from server tunning to coding for speed.

I didn't hear you mention GZIP as an option to speed up traffic between servers and browsers. Compressed content travels faster of course and almost all the new browsers can deal with GZIP. I don't have more facts about it but I've heard that is useful. even Brendon has a product (Web Booster) to help out with speeding applications, but I don't know if it apply for the new versions of Domino that includes GZIP support.

Anyways, there's a lot of best practices that can be implemented to seed up applications. Thanks for resuming them here!

Cheers!
