Hi!
You definitely have lot's of indices !!
May be too many !!
With so many indices you probably can't make a good use of the
key_buffer, that is why things could run slow although MySQL finds out
the index to use.
Schema normalisation and query optimisation would reap most of benefit
in your case.
