Hello
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.
