OVH SSD KVM vdisk (/dev/vda) performance varies a lot depending on hypervisor’s load.
some day early 2017,
Timing cached reads: 18348 MB in 2.00 seconds = 9184.72 MB/sec Timing buffered disk reads: 2338 MB in 3.01 seconds = 777.99 MB/sec
some other day May 2017,
Timing cached reads: 19078 MB in 2.00 seconds = 9550.77 MB/sec Timing buffered disk reads: 94 MB in 3.02 seconds = 31.09 MB/sec Timing cached reads: 19172 MB in 2.00 seconds = 9598.49 MB/sec Timing buffered disk reads: 194 MB in 3.08 seconds = 63.00 MB/sec Timing cached reads: 18410 MB in 2.00 seconds = 9216.01 MB/sec Timing buffered disk reads: 274 MB in 3.01 seconds = 91.06 MB/sec Timing cached reads: 18512 MB in 2.00 seconds = 9267.82 MB/sec Timing buffered disk reads: 346 MB in 3.13 seconds = 110.59 MB/sec
Online physical disk (/dev/sda) has stable performance every day May 2017,
Timing cached reads: 3488 MB in 2.00 seconds = 1744.73 MB/sec Timing buffered disk reads: 406 MB in 3.00 seconds = 135.24 MB/sec Timing cached reads: 3278 MB in 2.00 seconds = 1639.20 MB/sec Timing buffered disk reads: 404 MB in 3.01 seconds = 134.24 MB/sec Timing cached reads: 3338 MB in 2.00 seconds = 1668.96 MB/sec Timing buffered disk reads: 404 MB in 3.01 seconds = 134.28 MB/sec
| hosting provider | OVH | Online |
|---|---|---|
| remote console | yes but sucks (char issues if non us-english keyboard) | not on entry-level, XC2015 has one |
| ssh keys at install time | yes, that rocks | nope |
| install duration | fast | install process takes ages (bare-metal) |
| startup/reboot duration | fast *1 | reboot is slower (bare-metal) |
| IPv6 | available as of 2017 | partial as of 2017 |
*1 on centos vps at least, the VM does not reboot, you need to go to the console and restart your vps there…
