Very interesting, ok. Thanks for the further information, and for adding this topic to the FAQ - I did look for previous questions/solutions but this thread was the only thing I could find, so that FAQ entry will likely become more and more important as people migrate to gigabit networks.

The point is that the box has not enough CPU power: network + filesystem + eventually *software* RAID + disk. That's it.

For example, the Alt-F-0.1RC4-DNS-323-rev-A1B1C1.bin file is to be used on the DNS-323 rev-A1, rev-B1 or rev-C1. https://everrussian.amebaownd.com/posts/15426675. Serum fx vst download. Doom 3 v 3.1.1 no cd patch. Don't try to flash firmware if your box is not supported, e.g., the DNS-320-revB1 is not supported. Gautami telugu font free download.

Note: to ensure your product has the latest security updates and operates at optimal performance, it is recommended you update your product to the latest firmware after installation and to periodically check for new firmware releases. Updates can be found by searching your model name at or though the mydlink mobile applications for mydlink registered devices.
Alt-F is being developed and tested on a DNS-323-rev-A1/B1, a DNS325-rev-A1, a DNS-320L-rev-A1 and on a DNS-327L-rev-A1 hardware boards. Other models and boards are said to work.
This article will cover the installation of the Alt-F firmware and additional packages which are directly supported by the software. Subsequent articles will cover the installation of BackupPC and Gallery: Installing BackupPC on D-Link DNS-323 with Alt-F; Installing Gallery on D-Link DNS-323 with Alt-F; Installing the Firmware.

D-Link is not lying when it said that the box is GB capable -- it is, what it can't do is to saturate the link.

You can try to use iperf or netperf, which I made available as Alt-F packages exactly because this transfer speed 'issue' has been discussed ad nausea before (search the forum for it). Using iperf you can separated network and disk subsystems with a tested/reliable benchmarking tool [added: -- but remember, the reported throughput is attained at almost 100% CPU utilization, meaning that the CPU can't do other tasks such as reading or writing to disk.]

You can also increase the MTU and see how it affects throughput [added: Jumbo frames appeared to alleviate the CPU from the network software overhead, see eg this and this. Quote:

One of the early drivers for using jumbo frames was limited CPU speed. As I noted earlier, it takes over 80,000 standard Ethernet frames per second to fill a gigabit Ethernet pipe, which is a lot of CPU cycles. PCs with slower CPUs and bus speeds could not generate and pump enough Ethernet frames to fully utilize gigabit Ethernet's bandwidth. So network performance gains of 50% (!) were realized with jumbo frames on PCs with slower CPUs and bus speeds than the PCs in use today.

Here you have some benchmarks on the stock firmware: http://dns323.kood.org/information:benchmarks

I will not embrace on discussing this 'issue' again. [added: and just added a 'why is it so slow' entry in the FAQ, hope that's definitive]
