关键是我dd只有几M

看来虽然IP接近但是母机不同

我dd速度
dd if=/dev/zero of=test bs=512k count=4k oflag=dsync
643+0 records in
643+0 records out
337117184 bytes (337 MB) copied, 12.0001 s, 28.1 MB/s

IO倒还好 dd速度22MB/s ~ 30MB/S

虽然连BuyVM都不如 不过我能接受 至少比某家KVM宣称是SSD Cached的1.9M ...

关键是我dd只有几M

没觉得有多快

读取缓存而已……

如果缓存速度都才22-30这样的速度的话确实没救了

不过我用的挺好的 该说我已经用了很久了

仔细看了下 似乎说读取缓存是指那家KVM的。。不过即使这样也太那啥了吧 写入速度没缓存也不该那么慢的
