One of my harddrives (RAID 1 ) goes offline. I made the test with only 1 disk trasfering a 1.7GB file trought FTP and samba. Samba got about 24mb/s and ftp got about 45mb/s from the single disk both. Samba takes the twice the time than ftp, it is my bottleneck anyone has any patch/suggestion to improve the samba performance on freebsd? Thanks :) -- mmm, interesante.....
