Title:
  mythfilldatabase takes hours to complete

Status in “mythtv” package in Ubuntu:
  Fix Released
Status in “mythtv” source package in Precise:
  Fix Committed

Bug description:
  Background: 12.04 went to MySQL 5.5, which uses InnoDB by default.  So
  temp tables created by mythfilldatabase are now innodb instead of
  myisam.  These temp tables get written to disk at /var/lib/mysql.
  Because these temp tables are written to disk the ext4 journaler
  constantly runs against these files, causing a massive IO block.

  How to reproduce:
  1. run: mythfilldatabase --refresh all
  2. check iotop

  Example:
  Total DISK READ:       3.80 K/s | Total DISK WRITE:     322.99 K/s
    TID  PRIO  USER     DISK READ  DISK WRITE  SWAPIN     IO>    COMMAND                                                                
    329 be/3 root        0.00 B/s    0.00 B/s  0.00 % 99.50 % [jbd2/sda1-8]
  1091 be/4 mysql       3.80 K/s   83.60 K/s  0.00 %  0.34 % mysqld

  In the past this process would run in a few minutes, with this IO
  blocking going on it takes hours.
