iis webdav as file server, extremely slow upload speeds

I'm new to windows server 2003 and any intricate requirements, so there might be a simple answer for my question.  But this is what I've got:

windows server 2003
2 x 2.8 zeon proc's
1 gb ram
4 x 200gb sata hard drive in a raid5 config = total 600gb
iis 6.0  w/ webdav enabled

I think that should be all you need to know.

I'm trying to build a strickly file server utilizing webdav.  The problem that I'm having is that when downloading files from my server the upload speeds are extremely slow.  On average we're talking about 25-30k/sec with only one connection and then that get's distributed among additonal connections.  So 2 connections would result in 12-15 k/sec per connection.  Which I find unacceptable.

I've got a cable modem with a road runner business account, which should give me 3mb/384kb down/up.  I've got my modem hooked up to my 10/100mb 4 port router.  And then I've got 2 of the ports running to my server.  These are in 2 x 1gb Intel nics.  The nics are setup in an adaptive load balancing mode.

I've got the server configured only as a file server.  And the background services and system cache are given priority.  That's about all the changes I made after the installation.

I have no idea where to start to remidy this.  Please provide me with any information and guidance available.

You seem to have answered your question already... your upload speed is supposed to be 384kb, correct?  I would doubt that you actually achieve that level but you should test it and compare at http://www.broadbandreports.com/reviews/1573.

Your 1gb Intel nic and 10/100mb router do little to overcome the bottleneck caused by your ISP service.  If you really want to go the route of using webdav, you most likely will have to increase your upload speed by upgrading your account.

Doesn't 30 k seem low if my upload speeds are supposed to be 384?

Yeah, it does... you should pay the $10.00 to buy some tool points at broadbandreports.com and give a few of the speed tests a whirl... if you aren't getting at least 270 or so, then you need to track down what the cause is... first look at other people who tested within your area and see what they are getting.

Good luck!

Ok, now I'm confused, I ran those tests and here are my results:

TCP/Web100 Network Diagnostic Tool v5.3.3a
click START to begin
Checking for Middleboxes . . . . . . . . . . . . . . . . . .  Done
running 10s outbound test (client to server) . . . . . 376.01Kb/s
running 10s inbound test (server to client) . . . . . . 4.91Mb/s
Your PC is connected to a Cable/DSL modem


It actually seems like it's working like it's supposed to.  However, why would I get such a low speed when I did it myself?

You ran the "tweak" test, not the Speed test... what we're trying to see here is what your ISP upload speed is... so go to the Speed tests... and choose one that is located close to you.

For instance, I used MegaPath's San Francisco test and this was the result I got:
2005-05-08 05:29:19 EST: 4890 / 498
Your download speed : 5008262 bps, or 4890 kbps.
A 611.3 KB/sec transfer rate.
Your upload speed : 510882 bps, or 498 kbps

On the result page you can then enter your zip code and the "advertised" speeds you are supposed to be getting.  Once you do that you will be taken to another page which compares your results to others close by... you can broaden that search a bit by searching again but only using the first 3 digits of your zip.  (If you just want to see the over area results you can jump right to this page:  http://www.broadbandreports.com/archive).

If your results are not the same as your neighbors, then you should troubleshoot it with your ISP.  If they are the same... then you need to upgrade your service if you want better results.

Those were results from a speed test I ran.  I went to speed test, then i clicked on the show 316 speedtest sites.  Then I clicked on the HI link because I'm in Hawaii.  Then clicked start and posted the results.  Am I doing something wrong?

Thanks for the help!

Jeffrey Kane - TechSoEasyPrincipal ConsultantCommented:
Ah... I see what test you ran... the only problem with using the ones from the list of 316 is that you don't end up on a comparison page... don't worry about being in HI, you should still get decent results form any of the West Coast tests (Speakeasy, Megapath or Linkline)... then look at the comparisons.

By the way... you may find that using WebDAV isn't your best solution for what you are trying to accomplish... the reason the ADSL exists (lower upload than download) is so that ISP's can charge higher rates for content providers... which is what you are attempting to be.  It's usually more expensive to upload than download.  That seems to be changing, however, with the new Fiber Optic services that are coming into many markets... look around broadbandreports.com for more info on that.

Thanks, I'll try those sites out.  But the reason for using WebDAV is to be able to use SSL.  I'm simply trying to setup a file server with data encryption.  I'll post my results up soon, thanks.

Can you expound your needs for setting up a file server?  Who will access it? (are they authenticated on your domain? for instance).

What size files?  Do you need upload AND download from the client side?

Because there are many ways to increase your speeds with WebDAV... if indeed that's the right protocol to use in your case.  Generally bandwidth isn't an issue for webDAV because the protocol is usually used for collaberative content authoring... it's not really a good protocol for general file transfering -- hence the existence of FTP (or SFTP for secure transfering).

But if you still want to stay with WebDAV, check out http://www.bitkinex.com/  and there are a who lot of sources at http://www.webdav.org.

A couple of other thoughts...

WindowsNetworking.com always has good tutorials... go through this one and make sure that your installation didn't miss any important steps:  http://www.windowsnetworking.com/articles_tutorials/WebDAV-IIS.html

You can add a windows performance counter to see what's actually happening:  http://www.microsoft.com/technet/prodtechnol/windowsserver2003/library/DepKit/f1b65f71-c955-4ecc-81fe-3c5370d8b534.mspx
