When I changed over the XF, it was right from beta... importing from VB. The majority of tables when created where myisam, where now when XF is fresh installed, they're innodb. I am wondering how much difference there is, because it seems my host is telling me that my database is often getting stuck on an insert or read, which is creating a lot of my load issues. Is it this older DB structure that could be the issue? Can existing tables be changed to innodb with a live site?
