Performance Comparison As in this general article about checking for substrings using the contains method, we used the open-source framework Java Microbenchmark Harness (JMH) to compare the performance of the methods in nanoseconds: As we can see, the winner is Pattern with the CASE_INSENSITIVE flag enabled, closely followed by toLowerCase ().
