It'll be interesting to see how close their ASN.1 Infoset >approach can get to XBIS performance (at least in terms of the ratio to >text parse/generate speed; since XBIS is only Java at present and theirs >appears to be only C++ a direct comparison is difficult). Please keep in mind the following points: 1) That test was based on an early draft of the Fast Infoset standard (called X.695 at that time). The Fast Infoset draft has changed a lot since then. 2) The primary objective of that test program was to measure size. The speed results obtained are hard to evaluate, although they are always better than Xerces/C 2.2 parsing XML. I believe that the code could be optimized to achieve a higher speed, especially with the new draft of the Fast Infoset standard. Alessandro Triglia OSS Nokalva >- Dennis > >-- >Dennis M.
