How does that compare to other cloud servers?
- growt 11y agoYou can read my comment history for exact numbers. But for SSD storage it's not very good. Better than amazon EC2 though (t2 instance).
- edouardb 11y agoYou should have a look to the IOPS instead bandwidth root@instantcloud:~# fio --randrepeat=1 --ioengine=libaio --direct=1 --gtod_reduce=1 --name=test --filename=test --bs=4k --iodepth=16 --size=4G --readwrite=randwrite test: (g=0): rw=randwrite, bs=4K-4K/4K-4K/4K-4K, ioengine=libaio, iodepth=16 fio-2.1.11 Starting 1 process Jobs: 1 (f=1): [w(1)] [100.0% done] [0KB/18714KB/0KB /s] [0/4678/0 iops] [eta 00m:00s] root@instantcloud:~# fio --randrepeat=1 --ioengine=libaio --direct=1 --gtod_reduce=1 --name=test --filename=test --bs=4k --iodepth=16 --size=4G --readwrite=randread test: (g=0): rw=randread, bs=4K-4K/4K-4K/4K-4K, ioengine=libaio, iodepth=16 fio-2.1.11 Starting 1 process Jobs: 1 (f=1): [r(1)] [100.0% done] [22307KB/0KB/0KB /s] [5576/0/0 iops] [eta 00m:00s]

- antouank 11y agoDid the same test on a VM I have in DigitalOcean... ( Ubuntu, 512 MB droplet ) ~# dd bs=1M count=1024 if=/dev/zero of=test conv=fdatasync 1024+0 records in 1024+0 records out 1073741824 bytes (1.1 GB) copied, 2.35872 s, 455 MB/s
- hobarrera 11y agoAdd four spaces at the start of a line to mark it as code (both to avoid lines being merged and fixed-width font). (yes: it's just markdown here).
- reidrac 11y agoI'm not sure how good is the test as it depends on the IO levels of the host where the VM instance is running. This is a 1GB Debian Wheezy instance with regular HDD in Memset [1]: dd bs=1M count=1024 if=/dev/zero of=test conv=fdatasync 1024+0 records in 1024+0 records out 1073741824 bytes (1.1 GB) copied, 17.7142 s, 60.6 MB/s I checked the host and its load is average. DO's 33.6 MB/s sounds poor. [1] disclaimer: Memset hosting is my employer, I built some of this; but this is an honest test (personal VM running several services). EDIT: formatting EDIT 2: same test on a VM with SSD disk: dd bs=1M count=1024 if=/dev/zero of=test conv=fdatasync 1024+0 records in 1024+0 records out 1073741824 bytes (1.1 GB) copied, 3.48953 s, 308 MB/s Again, the host has average load.
