Eclipse 3.1M5a的性能并不理想,那么,在4月1日就要发布的3.1M6,在系统性能上,有多少提高呢?今天看到一个blog,提到了这个问题。从数据上看,3.1M6比3.1M5a有较大的提高,但是相比3.0,还有些地方不尽人意。
其中的一些数据:
JDT Core: - Performance: - 3.1m6 vs. 3.1m5a : - full build from 2% to 7.7% faster: - batch compiler 3% faster - scanner 31.8% to 36.7% faster - parser 13.8% faster - 3.1m6 vs. 3.0: - full build, still from 1.5% to 9% slower --> 3.1M7 - batch compiler 9% slower --> 3.1M7 - scanner 36.2% to 44.9% faster - parser 11%.2 to 14.8% faster - search & type hierarchies are faster than 3.0 (5% to 20% faster) - codeassist is about the same (if one disagrees, we need PR) - adding perf tests for CodeAssist, Scanner & Parser - reduced footprint of JavaModel (about 25% in some scenario) - code formatter now accepts mixed tab & space scenario (73104)
博客探讨Eclipse 3.1M6的系统性能。与3.1M5a相比,3.1M6有较大提高,但和3.0相比,部分地方仍不尽人意,并给出了相关数据。
