tomcat parameter tuning
JVM settings
l Generally use HotSpot JVM.
l Add -server.
l -Xms/-Xmx: Set the Java heap initialization and maximum value. The default is 1/64 physical memory and 1/4 physical memory, which generally does not exceed 80% of the physical memory, and these two should be set to the same, which is enough Just fine, too high will lead to wasted memory and long GC recycling cycles.
l -XX:NewSize/-XX:NewRatio: Set to 25%-33% of the total Java heap. Too high or too low will lead to invalid GC.
l -XX:PermSize/-XX:MaxPermSize: The maximum initial value of non-heap memory is set to 128M and 256M respectively.
l -XX:+AggressiveOpts: Use the latest optimization technology.
l Refer to the oracle official website http://www.oracle.com/technetwork/java/javase/tech/vmoptions-jsp-140102.html. There are other parameters that can be configured according to actual conditions.

The above introduces the tuning of nginx and tomcat in the welcome to nginx production environment, including the welcome to nginx aspects. I hope it will be helpful to friends who are interested in PHP tutorials.
