A concise guide to troubleshooting performance problems in SQL Server 7.
I know XSLT pretty well, or so I thought. I've always hated that XSLT limited you to one input document and one output document. For now you are limited to a single output document (this should change in the next version), but it turns out that there is a document() function built into XSLT which allows you to import nodes from as many input documents as you'd like. I wish I had known this a long time ago.
As of November 2000, MSXML is by far the fastest XSLT processor, if I am reading these benchmark results correctly.
