Is using verbose:gc and other print GC options an overhead to running java.

In my experience, only heavier output options such as

-XX:+PrintTenuringDistribution

-XX:+PrintHeapUsageOverTime

-XX:+PrintHeapAtGC

-XX:+PrintClassHistogram

have a negative impact on production systems due to increased verbosity. I usually use

-XX:+PrintGC -XX:+PrintGCDetails -XX:+PrintGCTimestamps -Xloggc:filename

in production with no impact and this way I can debug issues post-mortem.
