We are getting incredible poor performance on using the append option on the component tAdvancedOutputXML.   The first XML is created from a CSV source and  looks something like with one loop called Race and looks like below.  The second source is a CSV that has the ID field and another loop element (reason we can't use the MSXML because it appends all loops to the bottom where we need race in the middle).   The append actually appends to the top under id instead of the bottom in 4.0.3  and 4.2.3, however, in 4.2.2 it works correctly.   The problem is the append runs at like .01 rows per second.   We really need this append to run much quicker.   Any ideas?  Have tried temp directories, buffer increase, etc.   Right now, running XP on 4 gig memory, 32 bit, but soon going to 64 bit, 8 gig memory.   Also, need to open a bug on 4.2.3 in which the append doesn't appear to work..appends to top of student instead of the bottom like 4.2.2 does.
