I have a problem with __extremely__ slow performance using the Eudora mailtool. Both the executables and the mailbox are on (different) Samba servers. I have played with all the combinations of placements for executables and mailbox, and what it amounts to is that the slowness happens with the mailbox on a SunOS 4.1.4 Samba server. It doesn't happen on a Solaris based Samba server. As an aside I was also getting very slow preformance on another application which read images (readonly, sequential, small reads) from the same SunOS based Samba server - and it was fast on the Solaris server. I read speed.txt and using socket options = TCP_NODELAY improved the SunOS machine's speed by a factor of 5 (86 -> 17 secs). Unfortunately this did not improve the Eudora mailer performance !! I have thought about the different Suns' memory and basic speed, but it seems to come down to the Samba build (SunOS vs Solaris). (But I havn't excluded all other causes yet). Does anybody recognise these symptoms, please? Have I missed a key configuration parameter? Relevant global setiings (unravelled from include files), and [homes] section where mailbox sits. We have an NT PDC. [global] allow hosts = @pcs, @suns, @nt_servers browseable = yes create mode = 0750 dead time = 15 debug level = 1 domain logons = no domain master = no encrypt passwords = yes getwd cache = yes guest account = nobody hide dot files = no load printers = yes locking = yes mangled names = yes max connections = 0 min print space = 0 null passwords = no password server = <name> public = no security = server server string = Samba %v (%h-%d) share modes = yes wide links = no wins support = no workgroup = <NT Domain Name> writeable = no printcap name = /etc/printcap printing = bsd wins server = <IP of NT Domain PDC> preferred master = no local master = yes os level = 10 [homes] comment = Home Directory on %h writeable = yes browseable = no include = /local/lib/samba/valid_users.%h Paul Ostro University College London Hospitals -------------- next part -------------- A non-text attachment was scrubbed...

This is just guessing, but grab the latest samba, and then look at the various options for locking. I strongly suspect that your performace problems are related to locking issues.
