sorry i haven't tried using any of the Threading classes with ASP.NET,
however you might be able to change some other parts of the application to
solve your problem?

first of all is all the data changing in the xml file? If possible i've
found it easier to split out a large xml file into several smaller files and
use xslt on them to make a kind of view of the combined data.

try seeing if its possible to use the Cache object to store the data
(however if the cache has to be cleared every second i don't think this
would give you a large benefit).
