Just tried 3 times to set/reset:
query_cache_size: from 16777216 to 268435456
query_cache_limit: from 1048576 to 16777216
Whenever I restart MYSQL the Original settings return.
I have read that up to half of Memory available to a Magento Install should be allocated to MySQL and cache. Running on ESXI and can provide from 1024 to 2056mb for the Application.
I must be missing something...
Update: Digging into my.cnf -- seems to be the place to set variables more permanently
-------- Seemed to Take, but perhaps I don't want such a high number on Limit. Studying.
Why does not WEBMIN actually save changes of his sort? I recall the same isse relative to setting InnoDB settings a year ago or so.
