Hi Houdini Gurus,

Could somebody give me a clue on why telling mantra “-H localhost” gets the render speed down by at least 100%, as compared to plain “mantra”? It just doesn't make sense to me.

After doing some networked renders, thought that it's my 100Mb network that is slowing things down, and when I get a 1Gb switch things will get better. But the slowdown occurs on localhost, too, so networking should not be an issue here.

Any ideas?

Thanks,
Greg

Splitting up a render for multiple hosts adds overhead. I can't speak to the amount of overhead and it's impact on final render times, there's a lot of variables that can effect that that are local, such as infrastructure, what you're rendering, etc. Twice as long seems high to me, but not if you're talking about a trivial render. Splitting out over the network tends to be useful for more intense renders.

Cheers,

Hi J.C.

Thanks for your quick reply. It makes sense - I was doing a pretty simple render that takes 10 - 20 secs per frame on one machine.

Cheers,
Greg
