my first impressions are that it's an algorithm problem, not a what it's coded in problem. if the algorithm is o(n2) then you can't really escape the problem, even with hardware. as it is a very real problem for me (and therefore my customers) this is something i'll be tackling, probably starting in a few days. i'll post the results in due course. rick Michael Kay wrote: >>My expectation is that XML parsing can be significantly sped up with ... >> >> > >I think that UTF-8 decoding is often the bottleneck and the obvious way to >speed that up is to write the whole thing in assembler.
