DD Test Confusion

Posted On // Leave a Comment

Ok, so currently testing some code on a dedicated server I have,


Can anyone explain this to me?


[root@testserver ~]# dd if=/dev/zero of=test bs=64k count=16k conv=fdatasync


1073741824 bytes (1.1 GB) copied, 9.48912 s, 113 MB/s


[root@testserver ~]# vzctl enter 10


[root@test ~]# dd if=/dev/zero of=test bs=64k count=16k conv=fdatasync


1073741824 bytes (1.1 GB) copied, 1.09157 s, 984 MB/s


In the VM I am getting 1GB/s IO, does OpenVZ now cache to ram? Its been a while since ive setup a openvz based server.
