Is this > correct? How can I configure nfs caches? I haven't found any help in the mans! Please get your facts straight here. The FreeBSD NFS server is not "much slower", the problem is that the _DOS_clients_ are "much slower". The bottom line is that DOS and NFS _do_not_mix_. NFS is designed for systems that perform I/O like Unix systems. DOS performs I/O like a bootstrap loader (which it is), and interacts with NFS very poorly. What you should be doing is using a protocol that interacts well with DOS. In this case, the clear winner is the SMB protocol, as used by Microsoft Windows, and more importantly in your case also by the _free_ Microsoft Lan Client (available from ftp.microsoft.com). The server for this protocol is part of the 'samba' package distributed with FreeBSD. We use this combination extensively, and have seen performance well over 300K/sec using 8-bit ethernet cards. -- ]] Mike Smith, Software Engineer msmith@atrad.adelaide.edu.au [[ ]] Genesis Software genesis@atrad.adelaide.edu.au [[ ]] High-speed data acquisition and (GSM mobile) 0411-222-496 [[ ]] realtime instrument control (ph/fax) +61-8-267-3039 [[ ]] Collector of old Unix hardware.
