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.

> ssh has to set NONBLOCK otherwise it can, well, block - there's > no way for ssh to know a priori how much data it can write to a fd. I don't know anything about how ssh is structured, but I think it must be a bit more complicated than that. Ssh only sets O_NONBLOCK on an fd if isatty(fd) returns false, so it's able to function with blocking input and output if the relevant

Hello, Is it safe to change lines in plugins/quota/quota-maildir.c::maildirsize_write() from ? fd = file_dotlock_open_group(.., DOTLOCK_CREATE_FLAG_NONBLOCK, ..); to ? fd = file_dotlock_open_group(.., 0, ..); ? Rationale is: exim+cpanel frequently leave stale maldirsize.lock, but when quota plugin try to dotlock maildirsize, it do this with NONBLOCK flag and just once, so first lock fails with

If the host is slow in reading data or doesn't read data at all, blocking write calls not only blocked the program that called write() but the entire guest itself. To overcome this, let's not block till the host signals it has given back the virtio ring element we passed it. Instead, send the buffer to the host and return to userspace. This operation then becomes similar to how
