samba - Jan 2004 - problems with samba 2.2.7 installed on Tru64 with OS 5.1

Hi, 

I have installed samba (v.2.7) on a Tru64 server (OS 5.1) and the file transfer
is about 6 time slower that on another server with OS 4.0 and using samba
2.2.1a.

I have checked all network possible issues (the swith port are on both servers
configured for 100M/Full duplex and showing no errors to suggest a network
issue). I did run some fpt test and found no problem; the transfer is quite fast
and similar with the ftp transfer range on the other servers.

It seems the network performance issue are occurring only when utilising Samba.
Does anyone know if there is any problem with samba 2.2.7 installed on Tru64
(5.1)? Shall I install another samba version? If this is the case can anyone,
please, advise which version is best to install?

Thanks and regards,
