Performance has in fact been going down, albeit very slightly, with those settings by about 5-10%. I top out at 27MiB/s with all my clients. Thanks for your insights regarding kernel tunables - I already tweaked the kernel's TCP parameters (initial window size, rx buffer memory, etc.) to allow for better transfer speeds on my GBit link, and other file transfer protocols easily hit the speeds I'd like to see with CIFS - that is, more than 100MiB/s. Right now, even OpenSSH's sftp-server using sftp is faster for me (with considerably more load on the transfer's endpoints, of course) than smbd serving up CIFS. -- with best regards: - Johannes Truschnigg ( [email protected] ) www: http://johannes.truschnigg.info/ phone: +43 650 2 133337 xmpp: [email protected] Please do not bother me with HTML-eMail or attachments.
