Performance of Web Application

Hi,

Can anybody explain me yahoo web application in and out, like, database design, database server details, servlet engine, server details, the amount of data it handles. How it manages the requests and serves the requests so fast. 

I guess there will be millions of users for yahoo, and each user has a storage of 5MB. Given this much data, how is yahoo managing this much data and serving the requests so fast?

Clustering? In  the case of  google, clustering and good  algorithms I
guess.

This is way off topic. Do a search on Google (or better yet yahoo) to 
get the answer.

Much of yahoo is written in LISP  (I think). There are some discussions 
on ./ [slashdot.org] about this.

Hi there have you another service running on your port 8080 which of 
course is the default port.If so goto and edit (using your fav 
editor)your <tomcat-install>/conf/server.xml and change your port to 
anything above or greater than1024  as ports less than or equal to 1024 
will require superuser to access to bind (mine for instance is 6666)as 
mentioned in the README.txt /RUNNING.txt or Installation Files.

Thus Restart Tomcat 4.0.3 and change to the new port in the url i.e 
http://localhost:6666/index.html

Plz correct me if I'm wrong wortha try.

HTTP Status 503 - Server default is currently unavailable

Posted by Mark Hansen <kh...@yahoo.com>.
I'm trying to deploy Apache Tomcat/4.0.3.  It starts up, but when I try to
access index.html, I get the error message "HTTP Status 503 - Server default
is currently unavailable".

Can anyone tell me what might be causing this?

Thanks,

Mark
