Dedicated Server<BR/>FreeNAS 0.684b. Monitoring Network using FreeNAS WebGUI Graph option. 100Mbps. Disabled kernel tuning GUI option and manually adjust.<BR/><BR/>B. Client test (no special tuning) using large files 100MB-300MB<BR/>1. FC7-Test GNOME. Nautilus Drag and drop. Samba around < 27Mbps<BR/>2. FC7-Test console FTP. 97-99Mbp<BR/>3. Windows 2000-SP4 mapped drive. explorer drag and drop 52+Mbps. XCOPY 52+Mbps (Samba)<BR/>4. Linux console SMBCLIENT 80+Mbps. console stat states 9000+ Kb/s (Samba)<BR/><BR/>I will try further to see if I can improve without client tuning on Windows environments. However, I have no idea why the GNOME Nautilus desktop drag and drop stat is rather low.<BR/><BR/>STSThttp://www.blogger.com/profile/06291913215780605610noreply@blogger.comtag:blogger.com,1999:blog-1565531981620090589.post-52189866239537511942007-04-13T13:54:00.000+02:002007-04-13T13:54:00.000+02:00Kernel parameters are changed via the command line:<BR/>sysctl<BR/><BR/>You can check on the code (<A HREF="http://freenas.svn.sourceforge.net/viewvc/freenas/trunk/etc/inc/system.inc?view=markup" REL="nofollow">system.inc</A>):<BR/>, look for this function:<BR/>function system_tuning()<BR/><BR/>And here is an example of use:<BR/>/sbin/sysctl net.inet.tcp.sendspace=65536Olivierhttp://www.blogger.com/profile/08901361095735842069noreply@blogger.comtag:blogger.com,1999:blog-1565531981620090589.post-89019226131255924442007-04-12T18:17:00.000+02:002007-04-12T18:17:00.000+02:00Hi, my apology for leaving the comment here as I happened to reach this blog when searching google.<BR/><BR/>This is related to tuning and improvement to Samba under FreeNAS.<BR/><BR/>I have a working 2 disks FreeNAS 0.684b setup.<BR/><BR/>Under FreeNAS default setting, 100Mbit Ethernet. WinXP-SP2 client. FTP transfer is up to 99% line speed. SMB transfer is 60-70% line speed<BR/><BR/>I enabled WebGui Kernel tuning option and have manually adjusted/added FreeNAS SMB parameters to reach up to 70-89% of 100Mbit link.<BR/><BR/>I am unable to go further because I think I need to adjust individual kernel parameters to go further. . I could not find the file FreeNAS uses to change kernel tuning parameters. Is it possible to let me know where and how I can modify the kernel parameters individually inside the console during runtime so that I can test the changes. Thanks.SThttp://www.blogger.com/profile/06291913215780605610noreply@blogger.com
