Connection pooling options with JDBC: DBCP vs C3P0

Question

What is the best connection pooling library available for Java/JDBC?

I\'m considering the 2 main candidates (free / open-source):

• Apache DBCP - http:/

Answer 1

my recommendation is

hikari > druid > UCP > c3p0 > DBCP

It's based on what I have tested - 20190202, in my local test environment(4GB mac/mysql in docker/pool minSize=1, maxSize=8), hikari can serve 1024 threads x 1024 times to get connections, average time for each thread to finish is 1 or 2 million seconds, while c3p0 can only serve 256 threads x 1024 times and average time for each thread is already 21 million seconds. (512 threads failed).
