Here is some of the info you requested. I don't know exactly what you want from ktrace. Just browsing one share produced a ktrace.out that was almost 700KB in size, and I'm not going to send THAT to the list. ;^) system/user time? Are you refering to the cpu states that are listed in the top output? If not, what do you mean? Thanks again, -Chris This top output is while doing a copy to the FreeBSD machine. ********* top output: last pid: 45882; load averages: 0.04, 0.23, 0.40 up 1+08:54:43 19:51:09 45 processes: 1 running, 44 sleeping CPU states: 0.0% user, 0.0% nice, 3.1% system, 3.9% interrupt, 93.0% idle Mem: 20M Active, 19M Inact, 16M Wired, 5348K Cache, 7621K Buf, 532K Free Swap: 144M Total, 896K Used, 143M Free, 1% Inuse PID USERNAME PRI NICE SIZE RES STATE TIME WCPU CPU COMMAND 45675 root 2 0 3148K 1484K select 0:02 2.20% 2.20% smbd 224 root 2 0 1412K 856K select 1:17 0.00% 0.00% ppp 251 root 2 0 8276K 4864K poll 1:02 0.00% 0.00% squid 252 root 2 0 1188K 672K select 0:07 0.00% 0.00% sshd1 3044 moch 2 0 1192K 788K select 0:02 0.00% 0.00% screen-3.7.6 113 root 2 0 1764K 940K select 0:02 0.00% 0.00% named 42316 moch 2 0 1468K 1144K select 0:02 0.00% 0.00% irc-2.8.2-EPIC 311 cjm2 2 0 1068K 596K select 0:01 0.00% 0.00% fetchmail 170 root 10 0 1004K 492K nanslp 0:01 0.00% 0.00% cron 177 root 2 0 1304K 600K select 0:01 0.00% 0.00% sendmail 214 root 2 0 976K 596K select 0:01 0.00% 0.00% dhcpd 108 root 2 0 820K 436K select 0:01 0.00% 0.00% syslogd 146 daemon 2 0 788K 392K sbwait 0:01 0.00% 0.00% rwhod 45742 root 2 0 1224K 824K select 0:01 0.00% 0.00% sshd1 293 nobody -6 0 748K 252K piperd 0:00 0.00% 0.00% unlinkd 45459 root 2 0 1384K 872K select 0:00 0.00% 0.00% nmbd 167 root 2 0 892K 476K select 0:00 0.00% 0.00% inetd ********** samba config file: (the actual shares are defined in other config files, but all that are in those config files are the share definitions, nothing that would impact the speed of samba). # Global Samba Options...

Without info such as: top(1) cpu usage, actual samba config, ktrace(1) info, system/user time. how the heck can we help you? :) -Alfred To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
