=== *Description* ============================================================
As part of ksh93 update 2 project, uniq will be replaced with ksh93 internal 
implementation. 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.

[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...
