Dacentec network speeds
Hi guys,
I just bought a bare metal server(Supermicro X3440 8GB 2x2TB SATA Rent Only) from Dacentec a month ago and have been having unstable network speeds. For those who have had or currently own a server with Dacentec, what are your experiences with their network reliability and speeds.

@dacentec, Do you know what speeds I should be expecting? When I purchased the server, I was aware it was on a 1Gbps port, but nothing was specified about the network speed.
Open a ticket up with them and give them some info, they'll resolve it.
The network speeds are usually pretty good.
Looks really bad, and so does your I/O. I've got two boxes with them, the following is the one that is worse:
CPU model : Intel(R) Xeon(R) CPU L5420 @ 2.50GHz Number of cores : 8 CPU frequency : 2499.000 MHz Total amount of ram : 15886 MB Total amount of swap : 8063 MB System uptime : 56 days, 7:12, Download speed from CacheFly: 97.0MB/s Download speed from Coloat, Atlanta GA: 21.2MB/s Download speed from Softlayer, Dallas, TX: 39.0MB/s Download speed from Linode, Tokyo, JP: 7.59MB/s Download speed from i3d.net, Rotterdam, NL: 4.60MB/s Download speed from Leaseweb, Haarlem, NL: 20.6MB/s Download speed from Softlayer, Singapore: 8.60MB/s Download speed from Softlayer, Seattle, WA: 19.9MB/s Download speed from Softlayer, San Jose, CA: 27.6MB/s Download speed from Softlayer, Washington, DC: 42.7MB/s I/O speed : 160 MB/s (RAID0)
This is the better one:
CPU model : Quad-Core AMD Opteron(tm) Processor 1385 Number of cores : 4 CPU frequency : 2700.000 MHz Total amount of ram : 15949 MB Total amount of swap : 8031 MB System uptime : 56 days, 21:21, Download speed from CacheFly: 93.8MB/s Download speed from Coloat, Atlanta GA: 22.6MB/s Download speed from Softlayer, Dallas, TX: 66.4MB/s Download speed from Linode, Tokyo, JP: 12.6MB/s Download speed from i3d.net, Rotterdam, NL: 19.3MB/s Download speed from Leaseweb, Haarlem, NL: 19.0MB/s Download speed from Softlayer, Singapore: 7.97MB/s Download speed from Softlayer, Seattle, WA: 30.7MB/s Download speed from Softlayer, San Jose, CA: 31.6MB/s Download speed from Softlayer, Washington, DC: 59.8MB/s I/O speed : 84.3 MB/s (RAID1)
Thanks @tomle. I opened a ticket and was transferred from the support department to the network department, but ticket responses have been slower than usual. I was just told to run their version of the bench script (http://mirror.dacentec.com/bench.sh). Same results, as expected. Still no response.
Also, yeah, my I/O is atrocious. My USB2.0 flash drive is faster than that...
Make sure you enable writeback cache on the drives in your server. I remember seeing another thread where @MarkTurner was having issues with one of his customers and the issue with slow IO was that writeback cache wasn't enabled.
hdparm -W1 /dev/sdX
Try that and see if your IO improves at least.
Cheers!
@TheLinuxBug. Thanks for the tip! I will make sure I do that if I switch to linux. I'm currently running Windows Server 2012 R2. I ran those benchmark scripts in cygwin which shouldn't make a difference in terms of network speeds. Do you know if writeback cache needs to be enabled for Windows Server?
Chris just responded to the ticket.
I have no idea what could be limiting my downstream within Windows Server. Any theories?
This is one of my servers there.
@VPSSoldiers - thats a lot of swap:
Yes.
Which is best, dacentec $25 monthly or delimiter $20 monthly dedicated server? Both with 8gb ram.
@XxNisseGamerxX - thats depends on use. Dacentec give more disk (2x2TB vs 500GB), Delimiter has better connectivity and better location.
Also Delimiter gives you dedicated IPMI/KVM 24x7 rather than on demand (I know thats ironic considering your Java issues). For customers using management tools thats a bonus because they use various ILO tools to reboot their servers, pull management logs, etc

What is your AS / Test IP? I don't see it in your ads.
IPMI keeps coming up as a security issue.

And the battle begins.
No battle, just curious/interested. Maybe a delimiter customer can check at http://www.whatismyasn.org/
not a customer of them but from previous posts i believe AS7363 is linked to them.
Are you stating that Delimiter/Yomura/etc has 500 Gbps of IP transit uplink capacity in Atlanta?
LOL that was me writing something too quickly on my phone. I meant to say our server is including 500GB of disk space vs their 2x2TB, the cursor ended up in the wrong place when I wrote it.
Delimiter has access to 30Gbps of traffic in Yomura's datacentre.
[Edited: The 500GB reference is now in the right place]
Delimiter in Atlanta sits under AS7363
Hard to find delimiter test IP in your ads.

@markturner your peeringdb says you are up on the Atlanta IX, but I am not seeing you here: https://tie.telx.com/#participants, and I can't trace or ping to you from my 10 gig IX uplink.
I was able to find qps test ip pretty quick with google. Nice network.
In case others are wondering where the big ISPs sit:

Wow, this thread got interesting. Thanks for the help everyone! I decided to take the nuclear route and re-provisioned my server from Windows Server 2012 R2 to Ubuntu Server 15.04. Things seem to be fixed. It's still weird to me how something was limiting my downstream in Windows. There weren't and group policies set up that would affect network.
@dacentec: Just curious, are you one of the Chris's that I've been bugging constantly?
@MarkTurner: I've been really tempted to grab a server from you guys located in Minneapolis, but the servers that are offered only include a 1TB HDD. Do you guys have any plans to offer any servers more storage oriented, similar to the one I currently have (X3440 8GB 2x2TB SATA)?
No, but those guys are great.
They are! Do they live in the data center and switch off every 12 hours? LOL
It's one guy.
Watch foamy the squirrel tech support 3
And tech support 2 lmfao
100Mbps unlimited option yet?
Dacentec's support is fucking awesome. All who are comparing Delimeter/Dacentec, I would suggest you all to give Dacentec a try & you won't regret.
I haven't tested in a month or so, but I had burst speeds up to around 50MB/s (5-10 seconds) w/ something like 15-20MB/s "sustained" (some concurrent FTPs that I cancelled after some 5 minutes or so).
So considering prices, good speeds. Back in January-Feb, I had higher speeds, but couldn't say if it's just because of new 'neighbors' that are sharing my gigabit port, or if it's slowed down a bit overall.....
regardless, nothing to complain about w/ current speeds on my $20/mo server
