The performance benefits of MyISAM are exaggerated. Its advantage was that is was a decently fast and very simple engine which made it possible for MySQL to reach the market quickly.
MyISAM only gives good performance when you either have only reads or just one single writer. And even then it does not always win over InnoDB and PostgreSQL. And as soon as you get a mixed load MyISAM performance drops like a stone.
