Problem Description
Each invocation of
StringRedisTemplate.execute()creates a newDefaultStringRedisConnectioninstance, resulting in repeated initialization of non-static logger instances. This causes redundantLogFactorylookups that consume an additional 10–15% CPU overhead.Solution
Modify the
private final Log loggerfield inDefaultStringRedisConnectiontoprivate static final Log logger.Impact
10–15% reduction in CPU overhead for all Redis client command executions.
