Several performance-related properties apply to a cache server or application that
connects to the distributed system.
off statistics sampling saves resources, but it also takes away potentially valuable
information for ongoing system tuning and unexpected system problems. If LRU
eviction is configured, then statistics sampling must be on.
- statistic-sample-rate. Increasing
the sample rate for statistics reduces system resource use while still providing
some statistics for system tuning and failure analysis.
- log-level. As with the statistic
sample rate, lowering this setting reduces system resource consumption. See Logging.
