uhm, according to their benchmark io.js write performance dropped from 21mb/s to...

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.

Any numbers for node on ARM? I was told that recently v8 releases have had significant performance regressions for ARM devices by a JS dev at a meetup.

Can you give more information about this?

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.

Is there a ticket to follow to track this regression?

Is there a description of your benchmark machines / benchmark process anywhere?

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)!
