Community Review: DMB Hosting 512 MB OpenVZ
Hey everyone, here's another review of a low end plan (to see my first review click here: http://www.lowendtalk.com/discussion/145/community-review-goweb-256-mb-xen-pv/)! For this review I will be reviewing the a DMB Hosting VPS offer, specifically the 512 MB OpenVZ plan they offer.
The server is based in Scranton and comes with 512 MB of RAM (burstable to 1 GB), 20 GB disk space and 200 GB of bandwidth. Standard disclaimers apply, I am not affiliated with DMB Hosting and I used the one week free trial to test this VPS, performance could be enhanced due to it being a nearly free ($1) trial.
Basics:
DMB offer a range of templates including Debian, Fedora, Ubuntu and CentOS, all of which are available in both 32 bit and 64 bit). DMB uses a themed version of WHMCS for billing and a standard install of SolusVM to allow clients to manage their servers. Their TOS does not allow using IRC, torrent clients or hosting proxy sites which could be a problem for some users.
Support:
Initial setup was fast but unfortunately the welcome email did not include a SolusVM login address so I put a ticket in asking for the URL. The ticket was replied to within 2 hours (pretty decent) and I logged into SolusVM with no issues. To begin the benchmarking process I installed the Debian 5 32 bit template (they didn't seem to offer Debian 6 which was a let down) and left everything as it came.
Defaults:
Default RAM usage was very low with the server using about 15 MB with a stock Debian 5 install:
dmb:~# free -m
total used free shared buffers cached
Mem: 1024 15 1008 0 0 0
-/+ buffers/cache: 15 1008
Swap: 0 0 0
Default disk usage was also very low:
dmb:~# df -h Filesystem Size Used Avail Use% Mounted on /dev/simfs 20G 373M 20G 2% / tmpfs 512M 0 512M 0% /lib/init/rw tmpfs 512M 0 512M 0% /dev/shm
Basic Information:
/proc/cpuinfo showed four usable cores (I'm guessing you are not supposed to use it, there are probably limits).

/proc/meminfo showed some standard results:
dmb:~# cat /proc/meminfo MemTotal: 1048576 kB MemFree: 1033104 kB Buffers: 0 kB Cached: 0 kB SwapCached: 0 kB Active: 0 kB Inactive: 0 kB HighTotal: 0 kB HighFree: 0 kB LowTotal: 1048576 kB LowFree: 1033104 kB SwapTotal: 0 kB SwapFree: 0 kB Dirty: 260 kB Writeback: 0 kB AnonPages: 0 kB Mapped: 0 kB Slab: 0 kB PageTables: 0 kB NFS_Unstable: 0 kB Bounce: 0 kB CommitLimit: 0 kB Committed_AS: 0 kB VmallocTotal: 0 kB VmallocUsed: 0 kB VmallocChunk: 0 kB HugePages_Total: 0 HugePages_Free: 0 HugePages_Rsvd: 0 Hugepagesize: 2048 kB
Inode allocation was fairly high:
dmb:~# df -i Filesystem Inodes IUsed IFree IUse% Mounted on /dev/simfs 10485760 26148 10459612 1% / tmpfs 131072 4 131068 1% /lib/init/rw tmpfs 131072 1 131071 1% /dev/shm
vmstat showed values that seemed to indicate the node was under little to no load:
dmb:~# vmstat procs -----------memory---------- ---swap-- -----io---- -system-- ----cpu---- r b swpd free buff cache si so bi bo in cs us sy id wa 0 0 0 1033044 0 0 0 0 0 18 0 0 0 0 100 0
Tests:
Each test was run three times and the middle ranked test was picked.
The Cachefly speedtest showed very consistent results:
dmb:~# wget -O /dev/null http://cachefly.cachefly.net/100mb.test --2011-09-22 13:46:08-- http://cachefly.cachefly.net/100mb.test Resolving cachefly.cachefly.net... 205.234.175.175 Connecting to cachefly.cachefly.net|205.234.175.175|:80... connected.

Comments
Ping Tests (IPv6 didn't appear to work out of the box):
Disk IO was good, staying in the ~95 MB/s zone:
Geekbench (http://browse.geekbench.ca/geekbench2/view?id=485071):
Conclusion:
From testing this VPS I can see that DMB Hosting have the potential to become a great competitor to other LEB offers. Their speeds are great and their TOS may offer encouragement for users looking for a stable and poweful package with few abusers. Please give them a try and report on your experiences!
Thanks for reading, please give me tips and suggestions
