[erlang-questions] Erlang I/O and NIF

[alexander_koch_log]

Hi,

Came across this changelog https://github.com/basho/bitcask/pull/76/commits

I know there have been multiple discussion on this mailing list 
regarding pure erlang I/O implementation vs NIF based implementation. I 
also understand that using NIF would block the erlang VM, hence it is 
not an easy choice to decide which approach to leverage in an 
application where lots of disk I/O should occur. This gives the 
impression that Erlang may not be at all the right choice for any 
application doing lots of I/O, in your opinion, does this statement hold 
true ?

Most of these posts date from 2010 and I was curious whether this was 
still the case for Erlang as of today (as stated in the commit). Are 
they any work in the pipeline to improve disk I/O ? Is it safe to assume 
that "reasonable" performance is achievable when doing binary reads with 
erlang based I/O?

Thanks,

Alex
