Could Mysql cache cause a performance penalty, when invalidating
queries of a big Mysql cache zone?. I mean... I had a server with 16GB
of cache memory and when a big table full update was done... a
performance issue was suffered (seem not to be due to cache
invalidation!!)... apparently this performance issue was much more
notorious when the cache had been feeding some time and was near the
top of the cache (arriving to 16GB) than when the query cache memory
usage for example was much far more smaller... for example of 2GB
ram... of cached content....
Does it exist any kind of explanation for this sensation?.
