Our site get roughly 1M pv/day, and we use Tomcat for sure.
I couldn\'t find much information about jdbc-pool, not sure if it\'s stable enough for production. Anyone
Where I work we have a couple of systems running on the Tomcat pool.
I must say that initially it was sort of a pain to get a good understanding of all the options it provides and how their values actually impact performance and reliability.
After performing an initial trial and error phase, I have to admit that the Tomcat connection pool fits our needs perfectly. It seems robust and also have not caused any performance problems whatsoever.
With that said, I will definitely give HikariCP a try in my next project
