The experience made me very sceptical. It's hard to find real cases where hardware acceleration (or binary XML) makes sense for application work. If you're doing anything at all that's non-trivial (building an in-memory tree, sending transactions to a database, rendering into PDF, etc.) actual parsing is going to account for 1% or less (often much less) of total running time. That means that even if you a silver bullet that speeds up XML parsing by an order of magnitude, you'll be seeing less than a 1% speed improvement in your overall app. On the other hand consider a network carrier or major data centre that has to inspect, route, or otherwise process XML documents at wire speed as they fly past. That *is* a situation where accelerated parsing of some kind might make a difference. All the best, David [Date Prev] | [Thread Prev] | [Thread Next] | [Date Next] -- [Date Index] | [Thread Index] |
