Re: Re: Multithreaded XML file parsing?

OTOH, this objection assumes the files are either very large or being read byte-by-byte. If you know you can benefit by processing in multiple threads, you can get around the disk contention problem by using buffered readers or scarfing the entire file into memory all at once.

      Be aware that this may not be a good idea.  Your computer may have
multiple CPUs, but unless you're reading from a RAID or some other high
end storage device, your disk probably only has one read head.  If you try
to read several files at once, that head is going to be jumping all over
the place.  That will be much slower than just reading and parsing the
files one at a time.
