Hi everyone, I am hoping to get help with extremely slow performance of MyISAM to InnoDB conversion. Or find out if this type of performance is usual I have MyISAM table that contains - 3,299,509 rows and I am trying to convert it to InnoDB for the use with row-level locking, and I am getting insertion speed of 0.243 of a record a second while I am doing "INSERT INTO InnoDB_table SELECT * FROM MyISAM_Table. Your help is appreciated. Here is what my environment looks like. Hardware: SunBlade 2000 with 2GB processor connected to StorEdge A5200 with RAID5 on it.
