Will,

We are still actively investigating this issue.  If you would be willing to help with information, send me a private message and I will reply with the sort of information that may help us resolve this.

I can now unequivocally confirm this issue. While transferring a 961MB .mov file to and from my QNAP TS-809, I get an average of 35MB per second transfer speed with NIS 2010 build 17.0.0.136 installed. With NIS 2010 uninstalled I get an average of 105MB per second transfer speed. At first I thought the new build (17.1.0.14) caused the slow down, but my speculations were incorrect.

Disabling services in NIS 2010 does not make a difference. I only get the full transfer speed if I uninstall NIS 2010 or boot into safe mode with networking.

What is the status of this issue?

Let's hope that they will fix this soon. I have 55 days of subscription remaining. If this BUG isn't fixed by then, there will be no renewing of the subscription.

Regards,

I've gone to another product that doesn't interfere with my network throughput due to this issue. After having to put up with slow network speeds and after no update to this thread for a while, I decided that I'd had enough and uninstalled NIS.

If I could opt not to install the IPS component, I would use NIS again, but as it's all or nothing on the installation, I don't have that option.

Sadly, I find it unlikely that it will be fixed, as according to someone who posted earlier in the thread, it apparently existed in NIS 2009 also.

Huh... didn't realize my NAS was this fast, since I acquired it NIS2010 has been installed. With NIS2010 installed I'm lucky if 65% of my LAN bandwidth is being used. Without NIS2010, well, a picture is worth a thousand words.

I know this is the NIS/NA forum, but FYI 360 v4 beta exhibits the same issue.

[Ameya]

Yes, that is expected. N360 currently has the same IPS engine as NIS/NAV 2010.

I'll bet their driver can probably handle a megabit connection without much issue or degredation, but can't keep up with the bandwidth that a gigibit pipe demands. 

[metalhead82]

I think it won't allow any more than about 400mbit/sec on a gigabit connection.

I'm not quite sure how the driver works, but it certainly doesn't work very well. Deep Packet inspection shouldn't have that much of a performance 'cost' so I'm not quite sure what they are doing with the packets.

Still....let me know when it's fixed and I might reinstall it.
