I spent over an hour searching the web on this issue, and found that there are cases where DLLHOST.exe would cause 100% CPU Usage, but they are supposed to be fixed in my version, and there was no mention of this being caused by HTTP Upload. You would think if this was a problem with all windows IIS servers, there would be a lot of info on the web about it. That is why I am suspicious of an issue with the combo of Witango/IIS. I want to reserve judgement until I test it without Witango.

We use the http upload in the classified ad system we developed for the AutoTrader and I do remember when we were running it on Windows boxes, it was problematic -- almost to the point of making the system unusable. We even began development of a servlet to do the upload. The problem was solved by moving our production servers to Solaris...

I'd be very interested as to whether this is purely a Windows/Witango issue or if it relates to OSX and other platforms. I agree that it is totally unacceptable that there is anything more than a few percentage cpu usage, and this will significantly affect performance on my servers when I upgrade to Wi5 in the next week or so, as I have a number of apps that will require this service.
Maybe With has a comment on this one....?? Garth
Thats not the issue. The issue is having a solution for a client that is not savvy enough to use an ftp client. I already use webdav in such a way that they could connect with a webfolder from windows, or directly from OS X. But these are people that can only be expected to work with a single interface, and click a few buttons. Using HTTP Upload is very simple and suits that. But HTTP Upload has other problems, and this CPU Usage issue now knocks it completely off my list.

Why not just put up a ftp server instead of using http. Ftp protocol is
a lot faster than http for uploading and puts less strain on the server.
Windows 2000 comes with a ftpd built in and if your client doesn't have
a ftp client they can download a trial from like www.globalscape.com for
cuteftp.

I normally don't use http upload for many reasons, but I had to do a
quick and dirty solution for a client. They must be able to upload MP3
files to our servers. The files range from 10-20 megs. Before I put
this into production, I wanted to test the load it would put on my
servers. My app uses witango to accept the file argument, and write it
to a file where I want it. I am running Witango 054 and IIS 5 on
windows 2000. During the upload, the server pegs 100% CPU usage,
dllhost.exe and inetinfo.exe being the culprits. Witango only spikes
when the upload is done to write the file.
Since I have only used http upload with very small files in the past, I
have never noticed this. This is totally unacceptable. If I upload the
same file to the same IIS Server using IIS WebDav, it doesn't break a
sweat, 1-2% CPU Usage. I can't recall every testing this with other web
servers, does anyone else have any info with apache or Webstar?
It looks like I will have to write a custom desktop app for this
client's admin, which I did not want to do. If anyone knows of any IIS
5 tweaks that may help, I would appreciate it. My systems are
completely patched once a week.
