Re: Development Mode performance with Chrome

I would like to echo the sentiment of this request and in a similar
vein (and maybe this deserves a separate post) there is also an issue
with the performance of Chrome in compiled mode in the following
scenario:

I am using WebGL and when creating very large Float32Arrays (of maybe
90,000 elements) it takes an exceptionally long time. I am creating
only a few of these large arrays and it is instantaneous in Firefox
(less than two seconds as I would expect) but takes 8 minutes(!) in
the latest version of Chrome (and all previous versions). One thing
that I observe during these 8 minutes is that the page fault rate
(Windows XP) is about 160,000 page faults per second (for the entire 8
minutes) for the Chrome process and the VMSize is going up and down
all the time (varying from say 40MB to 50MB) instead of growing
monotonically. It certainly seems to be some kind of O(n*n) problem
and maybe even the garbage collector could be running as each element
of the array is allocated? I don't know.

Any ideas?

Thanks, Ed
