Hello Filip<br>
<br>
Thank you for the suggestions. I will run the tests from
browserbench.org and if I see a big difference I will submit a bug.
<br>
<br>
Thanks,<br>

Couple of thoughts:
<div class=""><br class="">
</div>
<div class="">1) That’s unexpected. You should file a bug on <a
moz-do-not-send="true" href="http://bugs.webkit.org" class="">bugs.webkit.org</a>.</div>

</div>
<div class="">2) SunSpider isn’t the best way to measure
performance anymore. Try one of the tests on <a
moz-do-not-send="true" href="http://browserbench.org" class=""><a class="moz-txt-link-freetext" href="http://browserbench.org">http://browserbench.org</a></a> instead,
they are more modern and we tend to use those instead of
SunSpider these days.</div>

<div class="">Hello<br class="">
<br class="">
I have two ports of WebKit. The first is based off of
revision 145828 and the second is based off of 184845. I
have compiled these ports for Linux x86 32 bit. I would
like to know why the port based on revision 145828 is
faster at running the JavaScriptCore tests. I have the
DFG JIT enabled for both, and I do not have the FTL JIT
turned on (obviously because it is not supported for 32
bit builds). I was wondering if maybe I need to enable
another setting the 184845 revision, but I think I have
turned on all of the JavaScriptCore enablements that I
can. I can post these if it makes sense for me to do so.
Here are the numbers that I am getting from the two
builds. I am just wondering if this is what I should
expect.<br class="">
