Performance

This application is built with performance in mind. On a mid to high range system, the transfer of each blockchain file will take only seconds. After the raw data is transferred, the SQL database is further processed to ensure good query performance. For more details see direct links between transaction inputs and outputs.

Here are some numbers collected on May 4, 2015 when the blockchain had 265 files.

System characteristics

CPU: Intel i7-4790 @ 3.60 GHz
