That thread could easily be wrong simply by thinking reasonably that, the machine they are porting out to may be quite a bit lower in specs. Just because you're shooting it to a network, doesn't guarantee faster renders if you're using slower machines to do the renders. I'm using 1 slave right now, it equal to my host machine and by utilizing both of them my renders have indeed cut in half or lesser. I don't have a renderosity account and doubt i ever will, but maybe ask those people for specs of their slaves vs hosts.
I think it was Vue 7inf where I personally found that rendering out 10 frames across 2 machines took longer than rendering those same 10 frames out to the parent machine.
Along the same thinking I also found a very high res image (say 5000x5000), if it rendered in say 1 hour on my main machine, would take close to 2 hours when splitting it up. Made no sense to me and it wasn't like the fast machine was 'waiting' around for the slow one to finish. It was just flat out slower. By alot. And it wasn't a network issue.. .the scenes appeared on both sides just fine, began just fine, saved out each block just fine. But something was definitely bogging down. In theory, the render should have AT LEAST been marginally faster but instead was significantly slower.
People chalked it up to 1 machine being a mac and 1 a PC. So I switched to both being PC's. Same issue. Never got it resolved.
After a few more tests and results like that I gave up and haven't used a render cow setup for some time.
My only other serious work with cows was prior to 6 and at that point, while the rendering was noticeably faster, the cow/setup kept bugging out that I also gave up.
I have used network rendering in like Carrara and other apps and always the speed boost is dramatic and you really do notice the difference having two or more machines machines plugging away. Vue, I haven't been so lucky.
With all that said, one time fact/claim that I can backup that e-on states is that the rendering in 10 is faster (on a solo machine at least). No question there. I timed various scenes in 8inf and 10complete and 10C finished about 20% faster on average. I'm back using 8 right now and I can definitely see a difference in how clouds particularly rendered faster in 10.
That I don't know, I cant think of a reason to render externally on the same machine im creating it on. I understand less processes rendering in a dos prompt and all, but why it would take so much longer does sound like a bug, I guess im spoiled with a farm.

It's slow for farms also, so you would probably want the bug fixed. Batch rendering comes in handy because there is no GUI taking up resources. The batch renderer (version 8 and 9) used to render the same speed on a local machine as the internal renderer did. Now the batch renderer is twice as slow on my system. Rendering to disk using the internal renderer is just as fast as render to screen. The "DOS" program just calls the Vue renderer to render something. It should work the same speed as rendering to a disk if just one computer is involved. It did before version 10. Something is broke now in Vue.
Luckily, users keep their old versions installed to compare with. Otherwise, how would a new user even know if a feature is working the way it is supposed to for knowing if it is a bug or not?
Some bugs are obvious, like the render stacking feature if you turn it off. Vue plays "grip of death" when it's disabled. But render time is hard to know if it's a bug or not. Until you render an image internally that takes 6 minutes, and batch rendering on the same computer (no nodes) takes 20 minutes. The render times used to be the same.
I don't know where you're getting all this info based on farm renders, we aren't having trouble with that right now at all, in fact its running pretty damn fast. Again though I am on a professional rendering farm and not something slapped together from 2-or 5 machines.
