Title: very strange problem
Post by: nrp on December 27, 2008, 08:52:24 AM

Hi there folks,

I have this weird problem while trying to run hfs.

My home network has 3 computers: one running vista, one windows xp and another one running linux/asterisk.

Today I realized that HFS on W Vista was extremely slow. Maximum of 68K per transfer "channel" on FIOS with 5 mbits/s upload.

First I though the problem was on HFS. So I installed another HTTP server but the results were the same.

Next I tried HFS on my XP machine and people were able to download stuff at 5 Mbits/s, my upload bandwidth. But on the Vista machine it was extremely slow.

My Vista is a legal copy, fully updated. I disables the firewall and anti virus, with no luck.

I started to believe the problem was on my network card. So I tried something different: I opened a WinSCP session on my Internet provider and uploaded a 4 gugabytes ISO file to it. And it worked perfectly, with very good transfer speed (almost all my bandwidth).

So, bottom line: on my XP machine, HFS works fine.

On my Vista machine the HFS does not work. Similar software don't work either. But WinSCP transfers work just fine.

Any idea what I should do to try to fix this problem with the VISTA machine? Any help would be very much appreciated.

Thanks

you could monitor CPU usage, and see if it reaches 100% (on a dual core system you won't see 100%, should get the double graph).

Thanks.

CPU is fine. I have a dual core machine and the machine is performing only the file transfer. Nothing else.

i don't understand from your answer if one of your cores is fully taken or not.
please report also how you got to know it.

No, machine is fine, both cores around 4% with 7-8% spikes.

that's the only idea i had.

what if you transfer in your lan?

Have you tried start an ftp-server on your vista machine and connect to it from vista/xp machines in the same lan?
Sometimes i have the same problem, no solutions so far...

I had similar problems, only if I often used  the hiberation closedown? ( I don't now the word in englisch set to sleep?) . But when I closed Vista (shutdown) and than startup every thing wend wel, and I had the full speed.

Just "hibernate" :)
Well I never use hibernate my self so that ain't the solution for me, maybe the solution for nrp?

On my Windows Vista I had to setup DefaultSendWindow in the registry.

Both HFS and Firefox seem to use this parameter.

IE7 doesn't need it.

After setting up DefaultSendWindow correctly, my speed is now ok.

I'd suggest having this in the docs.
