Re: [Jaffer-devel] Jaffer is much faster than Netatalk

Okay, after you called it a datapoint, I decided I better actually measure
it once with some degree of repeatability.

I have the same share under Netatalk 1.6.1 and
Jaffer-whatever-is-on-the-site. That directory on the server (RH 7.2, Java
1.4.1_02) looks like this:

www/
    com/
        latencyzero/
            11 folders
            3 files (tar & tar.gz)

Netatalk (afpd over tcp only) is listening on port 548, Jaffer on 5480.
Jaffer is running as root, in the background, and is spitting out data to a
terminal window.

The connection is high/variable-latency, 256 kbit up, 2-3Mbit down.

I mounted the Netatalk volume first, using the Finder. My Finder is set to
always open in a new window. The view is by icon.

I double-clicked on the volume, then com. Then I wait for the menu bar clock
to hit xx:x5 seconds, and double-click on "latencyzero". By the time it
finishes fetching the icons for the files (the folders show immediately), 12
seconds elapsed by the menu bar clock.

I unmounted the Netatalk volume and mounted the Jaffer volume, and repeated
the process. It took 5 seconds (actually, less, because it caught me by
surprise) to completely fetch all the icons.

I have not repeated this experiment, but it's consistent with my
(subjective) memory.
