I am running Gentoo on my server and samba 2.2.8a. Recently +I changed kernel version from linux-2.4.19-gentoo-r10 to +linux-2.4.20-wolk4.0s. And now I have performance issue with samba. Ok +many of you will probably say that move to vanilla sources...well I ried +it too and it didn't work. I have 100mb LAN and two computers (linux + +Windows2000).
