It seemed OK at first, but now everything is extremely slow. You should not set them to maximum available because you need other softwares to run in parallel. You can use -Xquickstart for initial compilation at a lower optimization level than in default mode. Later, depending on sampling results, you can recompile to the level of the initial compile in default mode. Use -Xquickstart for applications where early moderate speed is more important than long run throughput.

You can use -Xverify:none if you want to skip the class verification stage during class loading. However corrupted or invalid class data is not detected when this option is specified.

But this can only happen, when you are making byte code modifications youself. The JVM runs in two modes, -server and -client. If you use the default -client mode, there will be a faster start-up time and a smaller memory footprint, but lower extended performance. You can enhance performance by using -server mode if a sufficient amount of time is allowed for the HotSpot JVM to warm up by performing continuous execution of byte code.

In most cases, use -server mode, which produces more efficient run-time execution over extended periods. You can monitor the process size and the server startup time to check the difference between -client and -server.
