Ubuntu samba slow transfer speed12/25/2023 ![]() Snagged a 31G set of files a few weeks ago from a friend. It is in the repos or there is a snap package if you only want to touch storage in your HOME directory (which I seldom desire). To share a file, even a huge file, with one of my Linux buddies, I'll use Magic Wormhole. Right now, 14 things are scheduled for this week currently. I use 'at' to schedule future events all the time. Then I'll use 'at' to delete the file in 1-2 weeks automatically. If I need to make a file accessible to a few friends, I'll bury that file in a web server I control and send those friends the exact HTTPS link. It integrates with MS-Explore - full drag-n-drop and has a 2-pane layout for source and target. ![]() Windows has WinSCP as an scp and sFTP program. scp for files inside 1 directory that aren't already on the other side and rsync when an entire directory structure is involved. ![]() Again, if I don't have access to either side of the storage using NFS, then I'll use those to transfer. Scp and rsync feel a little faster than sftp. Because it is encrypted, there is overhead, but nothing as bad as sshfs. Sftp is natively supported by nearly all Unix file managers. Moving that complex setup to the system that has the data would be too much effort, so sshfs can be used for access while I have lunch or sleep. I only use it when a complex program/tool is on 1 system and the data to be input/acted on is on any other system, but not available over NFS. Getting the Windows UserID -> Unix uid/gid mappings setup was always a hassle. It was in Enterprise and Ultimate Win7 releases, but not Home or Professional. I understand NFS is part of some Win10 versions. I get better performance with NFS, but that is harder to use with Windows. and some didn't line up to make it easy to install and just work. At the same time, Win10 changed some of those defaults. With 20.04, a number of samba defaults changed. # this one is really slow#socket options = TCP_NODELAY IPTOS_LOWDELAY SO_SNDBUF=8192 SO_RCVBUF=8192įruit:wipe_intentionally_left_blank_rfork = yesĬode: samba 2:4.7.6+dfsg~ amd64I see 65-75MBps transferring files FROM Windows to Ubuntu using SMB v2.1. #no better than buf=131072#socket options = TCP_NODELAY IPTOS_LOWDELAY SO_RCVBUF=2097152 SO_SNDBUF=2097152 Socket options = TCP_NODELAY SO_RCVBUF=131072 SO_SNDBUF=131072 SO_KEEPALIVE IPTOS_THROUGHPUT #std#socket options = TCP_NODELAY IPTOS_LOWDELAY SO_RCVBUF=131072 SO_SNDBUF=131072 SO_KEEPALIVE ![]()
