[Wtr-general] Extreme slowdown moving from 1.4.1 to 1.5.1.1127

[Cain, Mark]

Are you running your tests from inside and IDE?  I saw the same slowness
moving from 1.4.x to 1.5.x when I ran (the same tests) from Komodo 3.5.
It was less apparent from Eclipse though...

Hi All, I've read through the archives I could find relating to
performance issues related to 1.5 but I didn't see any concrete
solutions or reasons why the slowdown is occurring. Running an existing
script using the profiler my execution time goes from 170 seconds to 425
seconds. Looking at the profiler output I notice the following: 

WIN32OLE#each is the top consumer in both profiles. In 1.5 it's taking
70.15 seconds vs 59.19 in 1.4. Not a huge jump, but noticeable when
running 100+ cases.

WIN32OLE#invoke is the number 2 consumer in both profiles taking 64.85
seconds in 1.5 but only 25.69 seconds in 1.4. This is obviously quite
significant.

Beyond the top two, the next highest in 1.4 is Logger#add taking just
over 12 seconds. However, in 1.5 I see seven additional methods taking
20 seconds or longer. The biggest hogs are Watir::Element#type at 62.64
seconds, Class#new at 42.49 seconds, Watir::Element#assert_exists at
41.68 seconds and Array#include? at 39.47 seconds.

I'm at a loss here. I'm running these tests on the same machine with the
same version of Ruby. I originally wanted to upgrade for the
click_no_wait functionality and modal dialog functionality but I can't
take this kind of a performance hit. Is there something obvious I'm
missing? I did notice the slowdown appears to be significant on pages
with lots of controls. At this point I'm probably going to backport the
click_no_wait and modal dialog functionality to 1.4.1 unless anyone has
an idea of what I'm doing wrong here.
