Why is Team Render slower than Single Render?

(1/2) > >>

Hello

I am a bit disappointed, I have connected a second iMac (4 cores) called "B" to my standard render iMac (10 cores) with Thunderbolt to render an image sequence.

The strange thing is that if I render with iMac "A" alone, the rendering process is faster than with team render.

Can someone please explain to me what I am doing wrong?

Many thanks, Best,
Katharina

Probably the size of the data transfer chunks is set too low, which means more time is lost sending data back and forth than is gained in rendering. Under Render Settings, Corona, Team Render, check if Automatic is set (the default). Try changing it to Arbitrated (experimental). If that alone doesn't improve things, lower the client update interval (send data back and forth less often) maybe try something like 20 or 30 seconds rather than 5, and raise the Max size of packet, try something like 128 or 256.

This can be resolution dependent, so the higher the resolution, the longer the interval and the larger the Max size of packet you want to try (basically if you see very tiny thin strips being rendered by TR, time to make these adjustments). Let us know which of the above helps!

PS - also you can render through TR Server which does not have this problem.

Hi TomG

Thanks for your fast response. I will  try the settings you said and also will try the "Team Render Server". With the "Team Render Server I had the Problem with the login of the Webinterface: I should enter "admin" as username, but what should be my password? The one for my Corona license is not working, also not the one for my iMac-User-Login. How di I figure out that password?

Hi TomG

I have now tested the first variant of yours.Once with Arbitrated (experimental) and the values 20 / 128 and another time with 30 / 256.

Unfortunately, both speech times are completely identical to the original attempt with the standard team render setting on "Automatic".

Therefore, unfortunately, no improvement.

TomG:
Curious that it made no difference at all. Any difference in the amount of RAM on both machines? (Could be the second machine is running out). Also, what are the render times, in case the slower machine just doesn't have time to contribute anything before the render completes.

For the password, it's something set within and controlled by TR Server. The default set by the TR Server if you don't change it is admin and admin, for user name and password.
