      Description

      JWarmup overcomes Java application warmup performance problem caused by JIT compiler threads competing with normal java threads for CPU resource at the same time when both the application (requests) loads up at peak and JIT kicks in for compiling tasks. By precompiling java hot methods during warmup, JWarmup can successfully improve peak time performance degradation.
