Martin Kleppmann commented on AVRO-1260:
----------------------------------------
(Of course I mean delaying applying this patch until 1.8.0, not delaying a
release. Sorry for the ambiguity.)

> I've made a few performance improvements to the Ruby Avro decoder. In my
> tests (decoding a complex record with many fields and nested records), I saw
> a 40% speedup on MRI 1.8.7 and a 20% speedup on MRI 1.9.3. The improved code
> also makes about half as many object allocations as before.
> Main changes are:
> * Using symbols instead of strings for the various schema types (there was
> actually a FIXME in the code for this, now fixed)
> * Added a few memoizations to avoid unnecessarily recomputing values
> I've tried to keep the API unchanged — {{Avro::Schema#type}} still returns a
> string, as users may be relying on the type ({{Avro::Schema#type_sym}} has
> the symbolized version). So I don't think this patch introduces any
> compatibility problems (as long as apps aren't relying on internals of the
> Avro library).
