-----BEGIN PGP SIGNED MESSAGE----- I have just discovered that my performance problems with samba (2.0.5a) dissapears if I build a non SMP version of the FreeBSD kernal on my dual 200Mhz PPro system. Using the SMP enabled kernal writes from the Windows98 explorer is painfully slow. A 121MB file takes around 30 minutes to copy from a local harddisk on the win98 machine to a samba share on the FreeBSD server. Using the exactly same kernel and samba configuration except commenting out the SMP stuff in the kernel config file the same copy takes aroud 20 seconds. Reads from the samba share are not noticably affected when using the nonSMP kernal. Here is my kernel config file: # # SMP-GENERIC -- Smp machine with WD/AHx/NCR/BTx family disks # # For more information read the handbook part System Administration - -> # Configuring the FreeBSD Kernel -> The Configuration File. # The handbook is available in /usr/share/doc/handbook or online as # latest version from the FreeBSD World Wide Web server # <URL:http://www.FreeBSD.ORG/>; # # An exhaustive list of options and more detailed explanations of the # device lines is present in the ./LINT configuration file.
