Name, Title and Company : Game statistics on my own web site
Opinion : I use Firebird since FB 1.5 version.
For my web side i use FB2.5 to provide game statistics.
DB size is 82 GB and use embedded server. Firebird is fast also on minimal environment like 4GB RAM! I use it also on company with very high load like 17 000 000 new records per day with updates to many tables - but this is better to describe in "case studies" then "Testimonials" which i include in near feature.
