Netgear ReadyNas DUO performance: conclusion
Hello everyone, After days spent on forums and attempts to reach solution for really horrible feeling from ReadyNas Duo performance speed, I feel an urge to make a summary of my experience. I bo...
hitcap - I am not sure if you are looking for help on the JF issue or not. If you are, maybe start over with more complete info on your network, and maybe we can help sort it out.
As far as I'm concerned you should have researched what you were buying before you purchased. And you should have resolved your issues when you bought it - when you might have been able to exchange it for the newer NAS.
Also, even if everything does support JF, there is no guarantee that speeds will improve. The physical network is still 1 gigabit after all.
JF reduces the packet rate on the network. That's all. This translates into fewer interrupts per second in the client CPUs. Sometimes that reduced CPU load improves performance, but often it does not. Even if it does help, 9K is not always the best max packet size. Wired networks tend to perform best with smaller packets, PCs often perform best with larger ones. You need to experiment some to find the right balance for your equipment.
Back in 2008, it was an excellent performer - here's one of the reviews: http://www.smallnetbuilder.com/nas/nas- ... o-reviewed It handled the biggest disks available (1.5 TB back then). But in the second half of 2011, much faster ARM products came out (from all the manufacturers, not just Netgear), that raised the bar on performance. Sellers of course cleared inventory of the older products as quickly as they could manage it.

If that is aimed at me, it is off target. I don't work for Netgear, and although I help out folks here, I have no clients. Some technical comments on jumbo frames below...

Agreed.

That's not Netgear fault.

Yes, it has the Infrant Sparc CPU. Though I think the duo was brought to market after the Netgear acquisition, so it was wasn't rebranded like the nv+.

I don't think that this technology is bad, but it's too old. I'm not sure, it have Infrant IT3107 / 280Mhz CPU?
