Performance: For MyISAM tables with bulk_insert_buffer_size values larger than 256KB* the performance of bulk insert operations such as multiple-row INSERT and INSERT ... SELECT operations has been improved greatly when up to a hundred rows are inserted at the same time. (Bug#44723)
Are bulk inserts uses heavy by vb? If so when?
I don't like upgrading when this are stable unless security fixes are part of the update. I'm hesitant to upgrade from 5.0.85 to 5.0.86 unless I can understand if this improvement even affects vbulletin's performance.
Maybe some MySQL experts here can shed some light?
