I wonder if some of the slowness is from running it through JS?
Perl has an extremely fast JSON parser (JSON::XS), would there be
any potential optimization in using an alternate view language like
that - or is most of the time spent elsewhere?
Another part is the Erlang to JSON conversion that is known to be
slow-ish. I don't know
which side of the conversion weighs more though. We are working with
the Erlang
community and developers to get a C-based JSON encoder into Erlang.
Since building
a view server is relatively straightforward, giving a Perl version a
shot is probably worth it.
Which Erlang version are you running? R11B-x is known for causing
view-build slowness.
R12B-3 and R12B-4 are good
