    rapidcache: block level
    http://www.rapiddisk.org/

    vmtouch: file level
    http://hoytech.com/vmtouch/
    https://github.com/hoytech/vmtouch

    rapiddisk wiki 还推荐了其它 ram disk/cache: http://www.rapiddisk.org/?incsub_wiki=rapiddisk

    目前在测 RapidCache(rapiddisk 里的一个功能):

    The RapidDisk collection is officially supported on the following operating system distributions:
    Red Hat
    CentOS
    Ubuntu Server
    openSUSE

    HP 也用:
    HP presented RapidDisk / RapidCache as part of a demo in the High Performance Computing and Open Source & Linux Technical Excellence Symposium 2014 with performance benchmarks as high as 40 Gigabytes per second! The presentation was titled: Addressing Database Performance problems using the HP Enigma RAM Storage Solution and was presented in Grenoble, France.


    测试了下,没成功。。。有用过或者有兴趣&测试成功的 V 有来分享下么~~
    (不像打错字的样子。。。这个项目 09 or 11 年就开始了 google 了下貌似也没找到同样的 error 。。。)

    感觉 sysctl 增大缓存增加写入延迟也可以达到类似的效果啊
    读取加速就更不用说了,本来空闲内存就都是缓存

    @ryd994 ssd+机械硬盘混合的机器,我只需要对机械硬盘的某文件夹或分区做加速, os 的 vm 管理无法对特定文件 /分区做加速吧?
