## gains.

## The query cache is a well known bottleneck that can be seen even when

## concurrency is moderate. The best option is to disable it from day 1
|
|
## by setting query_cache_size=0 (now the default on MySQL 5.6)
|
|
## and to use other ways to speed up read queries: good indexing, adding
|
|
## replicas to spread the read load or using an external cache.
