Paper on Selecting Server Types and Protocols

I ran across a well written paper about how to trade off the various types of servers and message types but I can no longer find it. I am pretty sure it was on this site.
Anyone know where it might be?
Thanks.

we have Choosing the message type and Smart Services articles.

Also you can check our docs site and old wiki site for additional articles

Thanks - That’s what I was looking for.
I would like to make a suggestion. Change the font used on the Wiki to make it easier to read. On my screens (1920 X 1080 LEDs) the letters fade into the background.
