Rob, why is it faster to upload all on one machine instead of going across a
LAN?  It seems to me uploading on the same machine should be as fast as a
file copy.  What am I missing?
 

Try a experiment. Try a fileupload on a single CPU computer, hosting 
your web app.
Then try it again for 2 machines connected by the same local LAN, one 
running the browser, one the web app.
Monitor fileupload time, % free CPU, virtual memory/paging usage, etc.
Report back the results.

Thanks,

I am testing file upload using Struts and FormFile but the upload seems
really slow. Uploading a 1,5MB file takes about 15-20 sec. and I am
running both the server and the browser on the same PC. Is this normal
or should the upload be faster?
   

Your upload will be slower all on one machine as opposed to going across
a fast LAN.
However, that does seem slow. I have uploaded a 650MB file in about 7
minutes across a LAN.
650MB/7 minutes  =~ 1.5 MB/sec.
Are you using Strust 1.1 and the default fileupload implementation which
is commons-fileupload ?
What browser, How much free RAM, CPU etc..
