During perfomance testing we discovered that uniq in ksh93 is slow. Upstream prepared bugfix already and it will be integrated in the next sync with upstream. *** (#1 of 1): 2009-08-31 09:18:30 GMT+00:00 <User 1-1SURPB> === *Public Comments* ======================================================== Updated synopsis per Roland's email to request-sponsor with message-id <<email address omitted>> [QUOTE] Additonally CR #6877392 ("ksh93 regresses uniq performance") should be fixed now (BTW: Can someone update the title to "ksh93 regresses 'uniq -c' performance", please ? It was only the "-c" option which caused trouble, in the normal mode the new "uniq" implementation both outperformed the old "uniq" implementation and the GNU coreutils one...) but we have to wait for the perf team to officially confirm this...
