From my tests with multi-Gb json streaming, the .getChar() is way faster than memory allocation to a new char[] via getCharArray(), specially because I can also see no other alternative to get the bytes out. There is one exception in case multiple iterations are performed into the same data and the char array is relatively small to be cached on the CPU’s L1 though.
