我发现升级到gradle 插件到3.0.1第一次打包很慢，第二次就很快

1. 我并没有使用fastdex插件
2. 第二次基本每次都是19s完成
3. 只不过我这次是在mac电脑编译的，没有试window 电脑升级后怎么样
4. 跟电脑性能有关系吗？
5. 3.0 里是不是做了大量的优化呢

3.0打debug的包会很快，资源编译默认使用aapt2支持增量编译，代码那块dex缓存的颗粒变成以.class为最小单位了，所以相对于2.x会快很多

那fastdex 在3.0 里做了哪些优化呢？

[typ0520]

目前的fastdex版本只做了3.0的适配

楼主是不准备维护了吗？对于集成了tinker的project，instant run不能用，打dex包还是很慢的

3.0打debug的包会很快，资源编译默认使用aapt2支持增量编译，代码那块dex缓存的颗粒变成以.class为最小单位了，所以相对于2.x会快很多

怎么知道这些信息的？
