MySQL Insert performance degrades on a large table

CREATE TABLE MyTable (
        id BIGINT PRIMARY KEY AUTO_INCREMENT,

From my experience with Innodb it seems to hit a limit for write intensive systems even if you have a really optimized disk subsystem. I am surprised you managed to get it up to 100GB.

This is what twitter hit into a while ago and realized it needed to shard - see http://github.com/twitter/gizzard.

This all depends on your use cases but you could also move from mysql to cassandra as it performs really well for write intensive applications.(http://cassandra.apache.org)
