cost much memory, Gc busy. use threadlocal will decrease memory use

* Given an object, returns the total allocated size, in bytes, of the
object and all other objects reachable from it.
* Attempts to to detect the current JVM memory layout, but may fail with
{@link UnsupportedOperationException};
*
* @param obj the object; can be null. Passing in a {@link java.lang.Class}
object doesn't do anything special, it
* measures the size of all objects reachable through it (which will
include its class loader, and by
* extension, all other Class objects loaded by the same loader, and
all the parent class loaders). It doesn't
* provide the size of the static fields in the JVM class that the
Class object represents.
* @return the total allocated size of the object and all other objects it
retains.
* @throws UnsupportedOperationException if the current vm memory layout
cannot be detected.
