我只是对基于 LXC 的 Hadoop 的性能有一些疑问。
所以我想知道是否有人以前有过这样的经历?内存或磁盘使用率等性能是否有任何令人印象深刻的改进?
如果您有任何测试数据可以与我分享,那就太好了。
好消息是,考虑到性能测试,lxc 几乎与 native 相同!
与VM(kvm)相比,我们这里有一些基本的结果:
CPU:native(lxc)and vm are almost the same MEM:VM performance is about 1/2 of native (lxc) DISK:VM write performance is 2/3 of native, read performance 1/2 NETWORK:VM has twice network latency than native
