That's a regression we'll probably have fixed in 0.6.1.
Note that I/O read performance is up 35%, from 19.7 mb/s in 0.4 to 26.6 mb/s in 0.6.

If you know that JS dev personally please ask him to file the bug (http://code.google.com/p/v8/issues/entry) or send any information he has about regressions to v8-users mailing list.
I don't think there were any bugs opened recently about perf regressions on ARM devices.
Thanks.
Keep up the great work, btw! I'm pretty excited to move up to Node 0.6 (probably-statistically-insignificant regression on IO-write regardless)!
