[Face flushed begin] Thanks for Greg "let" me take a second look at qsortB.c - there is paste-and-copy error there, so when it perform recursive sort, it calls glibc's qsort ... Really sorry, and feel a little bit gun-shy now ...
[Face flushed continue] After I re-tested it, now BSD qsort is the obvious winner in most situations. [Face flushed end] Regards, Qingqing ---------------------------(end of broadcast)--------------------------- TIP 6: explain analyze is your friend
