@happyfish100 我开发的一个统计系统正需要这样的功能,见 https://github.com/xindong/easy-total , 不过我Mac系统好像装不上(系统10.12.1),顺便帖下错误。 在 libfastcommon 里 ./make.sh: line 103: src/_os_define.h: Permission denied
cp: Makefile: Permission denied

昨天和apcu做了一下benchmark对比测试,发现二者性能相当。看来apcu性能也还不错呢。 |
感谢反馈,我已经修复了这个问题。 |
@happyfish100 如果共享内存被ipcrm掉,有没有什么方法可以在未释放共享内存的进程里知道是否被rm? |

1,基于共享内存的缓存目前已经有鸟哥的yac和apcu,实际上稳定性都存在一些问题,这个库和yac/apcu有何区别呢,benchmark可否和yac/apcu进行比较?
2,扩展对于windows是否支持,zts/nts版本是都支持么?
