better tcpip stack on hpux

[Shivkumar]

Is TCPIP stack superior/better on HPUX than Windows Operating System with regard to performance and efficiency ?

Thanks,
Shiv

This may have had some truth in it in the earlier versions of windows OS, circa win9x, as these have had no native networking support. But starting with Win NT and subsequently Win2K and WinXP, has had networking built in to the OS instead of being a patch on it. So right now, the question is : Are microsoft programmers doing a better or equal job programming network stacks than years worth of programming, most of which is open source anyway.

Also, unix, from the start, has been designed with IP networks in mind and built into the OS, whereas for windows, networking is a late comer into the game. But after all, windows also uses the same open source network stacks. It is a matter of implementation if you ask me. And tcp/ip being native to unix of any flavor, I believe it has some advantages over windows tcp/ip implementations, efficiency-wise if nothing else.

Shiv, Unix(HP-UX) built for networking and it carries native TCP/IP support. But in case of Windows, kernel should be patched to TCP/IP (not in 2000, XP...). I would bet, Unix TCP/IP stack is better than of Windows.

HPUX TCPIP stack is having several tunables to be tuned with ndd. ndd -h supported all supported parameters.

TCPIP stack is better in hpux compared with windows. HPUX is not desktop one. It has to request / service many requests. Performance is depending upon TCPIP stack for packet transfer.
