yes the update installed while setting up Autocad for the first time.
can you please do me a favor and run the code below and report the elapsed timer results that you will get. I'm executing the code on a p4 3.2 ghz computer,
autocad 2008 execution invisible: Elapsed timer (on): 0 days 00:00:00:953
autocad 2008 execution visible: Elapsed timer (on): 0 days 00:00:01:062
autocad 2011 execution invisible: Elapsed timer (on): 0 days 00:00:01:219
autocad 2011 execution visible: Elapsed timer (on): 0 days 00:00:19:531
Code:
(defun c:perf()
(vl-cmdf "'time" "r" "")
(setq i 0 p0 (list 0 0) p1 (list 0 1000))
(repeat 1000
(setq p0 (list (* i 150) 0) p1 (list (* i 150) 1000) )
(vl-cmdf "pline" p0 "w" "10" "10" p1 "" )
(setq i (1+ i))
)
(vl-cmdf "'time" "d" "")
(princ)
