I've been scouring the forum trying to find a definitive answer to this, but so far it seems there are mixed thoughts. Several posts say don't turn on Jumbo frames, that it causes problems. Then others say to absolutely turn it on and that VE Pro specifically takes advantage of jumbo frames.

I realize that JF's are an all or nothing setting meaning all the computers/switches have to use them or not. But I've also read that with current gen processors, it's possibly not even an issue?

I have 1 main 3.33 GHz Xeon 6 core Mac Pro running W7 (Bootcamp) and Cubase

I have 4 slaves all with i7 processors and intel network cards

I am using a Netgear Prosafe Gigabit switch.

Is it beneficial to use Jumbo Frames?

Thanks!!!!

Thanks Paul. I had seen that one too, but what is confusing is that I read several posts like this:

http://community.vsl.co.at/forums/p/36285/223392.aspx#223392

which seem to encourage jumbo packets. Seems like mileage may vary. I came across one where someone said said VE Pro "supports" jumbo frames, but I can't find it now.

Didn't know if there was an official recommendation from VSL or if we just try and see what works better?

Hi, 

What Martin Saleteg, one of our Software Developers, says in the thread: 

Jumbo frames should really only be used for bulk data transfer setups. They will give worse performance in a low-latency application.

I have to admit to being confused now. I'm a moron when it comes to computers, so I certainly wouldn't dream of contradicting anyone who has the least idea how things work. But I was having audio dropouts on my system until someone advised me to turn on jumbo frames, at which point they stopped. After seeing this thread I thought I'd check, and swtiched them off again, at which point I immediately started getting loads of dropouts again. My system isn't perfect anyway - I get occasional dropouts no matter what, and I'm thinking the built-in LAN on my motherboards may be cheap - but the fact remains that performance seems infinitely better with jumbo frames on.
