Large amount of web services call?

[howa]

I have clients which will call the server for record updating, and the
requests is expected to have 1000 req/s.

What kind of library is the most efficient for handling my needs?

E.g. XMLRPC, SOAP ect ?

THanks.

1000 req/s is high for any XML over HTTP solution.

You can go for it and just throw enough hardware at the problem.

Or you can go for a more efficient binary message format over
a permanent connection.

The most efficient would be some Datagrams, using an Applet to compose
the datagrams, and compressing the contents in binary format.

You won't be able to do much i/o to get that kind of volume. This
means you will need to be read-write caching nearly all your I/O.

The usual approach to keep ramping up the transaction rate is to use
multiple servers and a scheme to spread the load evenly over all of
them. You can see this with big companies. Every time you do a PING
you get a different IP as you are directed to a different server. You
just keep adding servers as needed to handle the load.
