Well, if you query large chunks of raw data and process it yourself, no wonder that you get faster response times...

However in your example you end up with a raw encoded transaction, in the "obvious" case you have a nicely decoded transaction in JSON format... if I needed high speeds + python I'd rather use something like pynode or let Armory do the parsing for me, if I were just trying out stuff, the few GB or RAM or SSD space for the index are much cheaper than me writing a raw transaction decoder.

I just added a blog post about faster blockchain scanning through bitcoind RPC calls, by replacing gettransaction queries per transaction with getblock false and DIY block and transaction decoding.

The blog post is here:

Feedback welcome.
