Hi all. I own the box for about 1 year now and I am quite satisfied. One problem I had from day 1 and still havent solved is the networking speed. My house has ethernet cable Cat6 wired all over and the box is connected through Gbit switches to the net. I haven't been able to get satisfying HD video streming performance through Windows (tested XP, Vista & 7). When streaming to PS3 or to the Popcorn Hour PCHA100 the performance is satisfying (ie no dropped frames, jerky video or unsynchronized sound).
I have firmware 1.07 and fonz's funplug. I have disabled the DLink bittorrent client and I use transmission 1.7. Using Total Commander in Windows the maximum rate I get when copying to the DNS is 20MB/sec but the bandwidth meter I have shows up to 80Mbit throughput. When copying from the DNS to the PC I get up to 6MB/sec in Total Commander and the meter shows 50Mbit throughput.
Today I found the time to connect the box directly to my PC with a Cat6 cable. The results are pretty much the same as before (when it was going through the switch to the rest of the house) with the only difference being 9MB/sec to the DNS and 4MB/sec from the DNS. The bandwidth meter shows the same numbers as before basically. Using ftp transfer gives similar results as well.
I also played around with Jumbo frames (disabling, 5k, 9k) but not a significant change at all and I tried disabling with a netcard that doesn't support jumbo frames, still the same. Finally, I almost always have problems when trying to delete a file from Windows in the DNS (ie a large movie, can take up to 2 mins to be deleted).
I consider the above to be less than expected performance in a Gbit wired ethernet environment (let alone when connecting directly to the PC with a Cat6 cable).
Any ideas on what might be wrong would be helpful

Your numbers are a little off - for example 20MB/sec does not equate to 80mbps, but - generally speaking, throughput on the DNS-323 is less than stellar, and more so on gigabit. The best I have been able to achieve is around 30MByte/sec using 9k byte jumboframes on a read.

Wow, what kind of settings do you have to see that? I consider myself lucky when I'm able to get 15MB/sec from my DNS-321. Different box, I know, but still. Twice the throughput? I typically see 10-12MB/sec.

Yeah well the 20MB/sec is not real and the 80Mbit the bandwidth meter shows is actually a burst and then drops down to 40Mbit.
For past couple of days either direct link to PC or to the network all I manage to get is 4-6Mb/sec from the DNS and 7-9MB/sec to the DNS. I guess I have to live with it ?!

>2GB file sizes, gigabit ethernet with jumbo frame and a fast disk subsystem on the receiving end - remember that is the best, not everyday throughput.

A couple of things to be aware of ...
File size affects throughput significantly - as the file size drops, so does the throughput - a single 2GB file will transfer faster than 1000 x 2MB files, even though the total volume of data remains constant.
The disk subsystem at the other end can be critical - I have two systems with gigabit ethernet and similar spec in terms of processor and memory, one of them a desktop, with an 80GB SATA drive cannot deliver more than 5~6MB/sec when copying from the DNS-323, the other, and IBM server with 2x250GB SATA in a RAID1 array will accept 30MB/sec.
Since I believe you are looking at what is essentially reduced performance - fragmentation of the disks may be one possible cause.

I will to defrag both ends and see the results

Not much lcuk really. Run fonz's disk utilities (worked perfectly and actually corrected quite a few errors) defraged my Windows disks but again same thing. If I do a fresh reboot or both Winodws & DNS the first few transfers will give me a 15-20MB/sec transer speeds. After a few hours it will again come down to the usual 4-6MB/sec. This from both WinXP and Win7

Does the speed goes back to normal when you power cycle the network switch?

Can you modify the samba parameters -- I found the samba read and write blocks set to ridiculously low levels on my Ubuntu box. Turning them up to 16k made a huge difference in throughput.
