of Computing Technology of the Chinese Emy of sciences and head of the "Dragon core 1" Development Team, revealed that the recently developed enhanced type of Dragon Core 2 has reached the level of "four" in the middle and low grades. Hu weiwu said that in 586, we developed godson 1, with a performance equivalent to, a leap from having to having none. In 03, we developed godson

was less than satisfactory. If you are always dealing with both of these files, then the second json.simple in both rounds is more appropriate for such scenarios. Jackson and Gson did not perform well on different file sizes. Unless the parsing speed is not considered, JSONP is nothing to be commended for. It behaves poorly on large files and small files compared to other libraries. Fortunately, Java 9 will soon have its native JSON implementation, believing that Jsonp's future

actual operation. The specific cause of the problem is not described. In addition, "GPU rendering mode analysis" displays the last 128 frames of data, but frame dropping may also result from a long operation between two frames. Therefore, we need to analyze the situation between frames to better understand the overall performance of the analyzed application. Two tools are provided in Android to achieve this purpose: 1. systrace (this tool pitfall me
