I was copying from my server to vista and getting some very slow speeds.  I searched the forum and tried the fixes (I already had SP1) and still I was only getting about 11MB/sec.  I searched google and found this.  With MCE running there is network throttling keeping the speeds low.  I edited my registry and now get about 70MB/sec reading from the server.  I don't have a cache drive so I'm only getting about 11MB/sec to the server but that's ok.

You can also try turning off remote differential compression.  http://bestinfo4u.blogspot.com/2008/12/get-better-file-transfer-speed-in.html  I found this and tried the same file a second time and it seemed make to the server to around 12.5MB/sec.

 

In the end if you do a lot of transfers a cache drive is probably the best solution.

This is a terrific find, and I imagine many users will be thanking you shortly.  I hope to add this and the Vista RDC tweak and the IP6 turn off to the Improving unRAID Performance page shortly.

 

Credit should also go to ReneV for his initial find of this and reporting of it here.  I don't know why we overlooked that post, perhaps because of a more technical (and less understood?) presentation.  At that time, I didn't have time to research it, so put it (buried it!) on my to-do list.

ReneV ... I don't know why we overlooked that post, perhaps because of a more technical (and less understood?) presentation.

 

Less understood by ...? 

I actually did the second portion of that post because it's a dedicated HTPC and it didn't do much I'll have to go back and try the system responsiveness update.  Since my original post deals with throttling.

i'll have to go home and try this....with windows media player or VMC running in the background i get horrid transfer speeds....i think your reg fix should be the only one needed (after reading ReneV's post), since it completely disables throttling.

 

 

Hi,

My read speed with vista SP1 was around 12MB/s. Now it is around 68MB/s. The only thing I did was to disable IPv6. You should check this as well.

Turning off throttling helped w/ the slowdown of speed while transferring a file i experienced when running WMP or VMC....but neither help in increasing the transfer speed from unraid to my machine...still about 30MB/sec.

 

When i was using Windows Server 2003, i used to get about 65-70MB/sec....

 

Well, more RAM on the vista machine helped (i was only using 1GB b/c 1 stick had gone bad).

Going to 2GB ram and im up to 60/70MB/sec!

 

I dunno which tweak did it lol (b/c i did a lot)
