I made an attempt to see about the various speeds available with different Ciphers were like I didn't use any solaris hosts yet, as I want to ensure there was no hidden snapshot or the like involved. Source host openssh 7.4p1 Windows 10 running cygwin Destination host openssh 7.5_p1-r1 Gentoo linux 4.9.10 kenel The gentoo host is actually running in a vbox vm on the same windows host ... they have bridged networks setup. ============================================= Using default cipher (Not sure what that is or how to find out. But the default list below does not include `arcfour' so It would not be arcfour The list of defaults is: sshd -T |grep [Cc]ipher] [email protected],aes128-ctr,aes192-ctr,aes256-ctr, [email protected],[email protected] (on both ends) (NOTE: I believe they are listed in order of preference so I guess that means it would be chacha...) time rsync -avvz ./isos g1:/ real 32m55.694s user 5m9.918s sys 9m41.603s sudo du -sh /isos 29G /isos du -sb /isos 30833797326 /isos 28.7 GB ============================================== At destination host remove the test data: rm -rf /isos Now using arcfour Specified in the cmdline on destination host,but I had to add arcfour to the defaults on the Source host /etc/ssh/sshd_config time rsync -avvz -e 'ssh -c arcfour' /isos / real 34m1.297s user 4m22.176s sys 7m30.078s du -sb /isos 30833797326 /isos 28.7 GB ============================================== As you see the default Cipher was barely a minute faster than the arcfour over 28.7 GB of data. Absolutely NOT a diffinative test in any way but should at least show that on this network arcfour is likely to be no faster than the defaults in recent openssh versions. I still have to run an mbuffer/tamp transfer to see how that compares. _______________________________________________ openindiana-discuss mailing list [email protected] https://openindiana.org/mailman/listinfo/openindiana-discuss
