Our previous software suite (pre-FreeBSD) used samba for fileservice on a number of workstations (Sun IPX, Alphastations), and DOS clients using low-performance ISA ethernet cards. Our primary demand on the network was directory lookups (finding the next filename in a spool directory with up to 700 files in it) and bulk writes to the server (several MB in a solid chunk). Unfortunately, the last system of this type around now is out at our field station surrounded by a foot or so of mud, and I'm not inclined to make the hours drive there to get some numbers 8) however I know we were getting over 400K/sec out of a 486DX2/66 using a WD8003 to the IPX, and closer to 600K/sec when we were testing the DEC DC21040 cards in a PCI 486DX4/100. Read performance was never an issue for us, but in "general use" around the office there were no complaints about performance when I ditched the last OS/2 server for FreeBSD/Samba. I'm particularly amazed that PC-NFS works well for you - we were seeing really atrocious write performance from it (and most other NFS clients) when we tried it. (~50-70K/sec was common) Your mileage may, and obviously does, vary 8) > Martin Cracauer <cracauer@wavehh.hanse.de> - BSD User Group Hamburg -- ]] 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.
