What I /think/ it's doing is, when it chooses what things to put on what floors, it is -- in both my example and my real code -- choosing the shorter sequence of ascents as the right one.

I just tried to do a framerate test at maximum image size, which is about 10MB per image.
20:02
< ErikMesoy>
*Camera eyes Derakon
20:02
<&Derakon>
And we can collect data that quickly.
20:02
<&Derakon>
But transferring it over the 10GBit link happens at like 10FPS instead of the 100FPS that we collect at.
20:02
<&Derakon>
In short our network performance is somewhat laggardly.
20:02
<&Derakon>
I wonder why.
20:03 * Tamber hides the seed-box
20:06
<&Derakon>
Ha. We're only using 6% of the 10GBit link.
20:07
<&Derakon>
...less, actually.
20:07
<&Derakon>
I wonder if packet size is killing us somehow.
20:08
<@froztbyte>
check what your pps rating of all your gear is
20:08
<@froztbyte>
if you have useful switches around
20:08
<@froztbyte>
they should be able to tell pps utilization
20:08
<&Derakon>
We can do 400FPS with much smaller images (256x256).
20:08
<@froztbyte>
(vs traffic load)
20:08
<@froztbyte>
(pps is packets per second)
20:08
<&Derakon>
So it shouldn't be a packet rate limitation.
20:08
<@froztbyte>
it can still be
20:08
<@froztbyte>
network hardware can have some very weird bugs
20:09
<@froztbyte>
for instance, you can run into something that is the *exact* right kind of thing to screw over fast-forwarding code
20:09
<&Derakon>
...ohh, actually, it might be an issue with the work the receiver side does each time it gets a new image.
20:09
<&Derakon>
Processing the image takes longer; if it's holding the network link hostage while doing that, that could account for the slowdown.
20:09
<@froztbyte>
yeah probably
20:09
<&Derakon>
(Especially, trying to display a huge image takes a lot longer than trying to display a small one)
20:09
<@froztbyte>
just throw things into memory or onto an SSD cache?
20:10
<@froztbyte>
so that you can receive faster
20:10
<&Derakon>
I'm going to try spinning up a new thread for each received image instead. Or set up a producer/consumer thing.
20:12
<&Derakon>
Hm, no, that's not it...
20:14
<&Derakon>
It does occur to me that we're attempting to generate effectively an 8GBit stream (10MB/image at 100FPS) and have only a 10GBit link; network overhead might make this impossible no matter whate we do.
20:14
<&Derakon>
Er, what.
20:14
<&Derakon>
But we should be able to do better than the current <1Gbit utilization.
