Great news !
After applying the LLInt patch I've got better results:
Thank you very much for pointing me to the right direction !

I have not experimented with V8 and QtWebKit, and I don't know how much work
it will be to reintegrate that, but I think it has not been maintained for

but only the first generation JIT. The second generation DFG JIT for MIPS is
in WebKit trunk, and so is LLInt for MIPS. LLInt is the low level interpreter
that is used when JIT doesn't look profitable. Neither has been cherry-picked
for Qt 5.1 nor QtWebKit 2.3 yet, but I am expected it to be in Qt 5.2.
It shouldn't be too hard to cherry-pick MIPS LLInt which should be somewhat
faster than without, but the DFG JIT code is much more invasive and would take
more effort. If you want to give a try at MIPS LLInt you can start at
