Atry pointed me to latest release (0.8.7) of his protoc-gen-as3 library. I re-ran my tests to see if it brings any performance improvements – and it does!

Deserialization times are very similar to 0.8.4 which I used previously. I would assume any differences are statistical errors.

Deserialization
AMF 3 Protocol Buffers
Class: Small Medium Large Small Medium Large
Average:
(ms)
445.96 962.16 1313.68 326.26 962.00 1435.76
Std dev:
(ms)
25.23 24.35 15.96 4.69 4.38 9.96

Serialization times are greatly reduced – PB library is now 3.5 times faster then before for small messages, over 4 times faster for medium and 4.5 times faster for large. It is still slower then AMF3, but I for most use cases the difference is now negligible.

Very good news!

Note: Tests were ran on MacBook Pro, 2.26GHz Core 2 Duo, 2GB RAM.
