Thanks a lot for the update, I was eagerly awaiting for it :)

The build was a snap, so I just went ahead and replaced the previous 
binary I was using (beta3).

Out-of-the-box, everything seems to work fine... except that 
performances seem to degrade sharply over time. After a couple of 
ApacheBench runs, the throughput of my Lua web server drops by over 
50%.

Only the luasocket binary has changed. Replacing it with the previous 
version brings things back to, er, "normal".

How does the "improved:tcp:send(data, i, j)" impacts existing code? Was 
it not working the same way in beta3?

Here is my current "send" method:

        local anIndex = 1
        local aSize = 0
        local aRemainder = 0

        while true do
                anIndex = anIndex + aRemainder

                aSize, aStatus, aRemainder = self:socket():send( 
aValue, anIndex )

http://dev.alt.textdrive.com/file/lu/SocketWriter.lua

I'm not quite sure what needs to be adjusted (if anything) to make it 
work with the new, improved, tcp:send()...

Looking at etc/dispatch.lua, it seems that the send invocation looks 
like this now:

        first = (first or 1) - 1
        local result, error
        while true do

            result, error, first = tcp:send(data, first+1, last)

Is that what needs to be changed?

I'm quite confused :/

Thanks for any clarifications :)

Cheers
