That's crazy! I'll try to get a shark profile.

Not directly related to bug 469347. We should check first if this is a Mozmill problem.

Brendan, is this Shark profile helpful to identify why we are so slow on the sunspider test when Mozmill is installed?

Comment 4

[Mike Shaver (:shaver -- probably not reading bugmail closely)]

Which shark profile?  And which sunspider test?  The loop test in the URL isn't part of Sunspider, afaict.

Oh double sorry. I meant the loop test and further forgot to point to the shark profile. Here it is: http://mozilla.hskupin.info/mozmill.mshark

WFM on current trunk and the MozMill 1.5.5 extension installed.
