https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=271065 --- Comment #5 from Ivan Rozhuk <rozhuk.im@gmail.com> --- > Annoying, because it's mentioned in the sshfs man page: https://linux.die.net/man/1/sshfs .

I will fix that. > Where do you see that comment? * fusefs currently reads ahead no more than one cache block at a time. > Could you please try this patch and tell me what you find? unique: 318, opcode: READ (15), nodeid: 5, insize: 80, pid: 63228 [02387] READ [02388] READ [02389] READ [02390] READ [02391] READ [02392] READ [02393] READ [02394] READ [02395] READ [02378] DATA 131076bytes (186ms) [02379] DATA 131076bytes (208ms) [02380] DATA 131076bytes (208ms) [02381] DATA 131076bytes (209ms) [02382] DATA 131076bytes (209ms) [02383] DATA 131076bytes (226ms) [02384] DATA 131076bytes (264ms) [02385] DATA 131076bytes (275ms) [02386] DATA 85bytes (275ms) unique: 318, success, outsize: 1048592 This is work.
