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)
