Comment (by warped <warpme@…>):
Ian,
Thx for this post. Your insights intrigued me so I do quick research on
bugs.mysql and it seems that query_cache has still unresolved problems.
Many ppl are suggesting turn-off this feature and what is more important -
query_cache_size=0 is not enough to completely turn it off as
query_cache_type is defaulting to 1 - and being non-zero still acquires
internal DB spin-locks.
It is highly recommended to set both (query_cache_size and
query_cache_type) to 0. I do this and will observe system stability. Thx
again and good luck !
