In certain situations sftp download speed can be much less than that of scp. After many days of trying to find the cause finally I found it to be the tcp nagle algorithm, which if turned off with TCP_NODELAY eliminates the problem. Now I see it being discussed back in 2002, but it still unresolved in openssh-4.2 :( Simple solution would be to add a NoDelay option to ssh which sftp would set.

And while we are at it, can you please comment on these patches as well, originally submitted around one year ago. Oh, and I think we can agree, that the secsh-filexfer standardization is dead, so there's not much point in trying to support newer protocol versions, which don't have statfs anyway. Thanks, Miklos ----- This is needed to be able to support statfs operation on an SSH

Here's a patch that adds support for the creation of hard links over SFTP. Hard links are not used very often nowdays, but they do still have their uses and this is currently the most often requested improvement for SSHFS. To detect hard links the st_nlink, st_dev and st_ino attributes are usually used. I'll also post patches adding extensions for these and other attributes. Please

Dear all, I am looking for the status on the hardlink patches that were published on this list last february by Miklos Szeredi? I'd really like to have hardlink support in sftp. This would in turn enable hardlinks in sshfs and make incremental rsync backups to remote filesystems possible. can someone tell me if these patches will be incorporated in openssh? The patches can be found under

This is needed to be able to support a rename() operation conforming to POSIX in the SSH filesystem. With the rename operation defined in the SFTP spec, this is impossible, since in case the target exists it's not possible to perform the rename+unlink atomically.

This time the problem is that the ssh server only sets TCP_NODELAY for interactive (tty) sessions or if X11 forwarding is enabled. Neither of which are true for the use of the sftp subsystem. This hurts upload performance for sftp/sshfs. I'm not sure why this hasn't cropped up earlier. Were there any TCP_NODELAY related changes in the sshd code recently? Is there a reason not to

Couple more bikesheddy things: Is there ever a reason to use a non __builtin_const_p(perms)? Maybe that should be a BUILD_BUG_ON too BUILD_BUG_ON(!builtin_const_p_perms) My brain of little size gets confused by the BUILD_BUG_ON_ZERO(foo) + vs BUILD_BUG_ON(foo); as it just seems like more text for the same content. Is there any value on the "_ZERO(foo) +" I don't understand?

Hello, Renaming a file via sftp on an sshfs mount resulted in a failure with errorcode 38 (ENOSYS). This is reproducable with openssh release 4.9p1 & 5.1p1 in combination sshfs 2.2 (latest releases). Investigation revealed that sshfs only implements the rename()-call and not the link()-call (used by sftp-server). Attached is a patch to perform the rename()-call upon a failed link(). The
