I wear many hats at my workplace.

Primarily a Database Developer, but also programmer, web designer, DBA, sysadmin, and general office bitch.

I work for a small custom software house in Sydney, Australia. We use all manner of tools - but mainly MSSQL and a Rapid Application Tool called eDeveloper uniPaaS Magic XPA.

comment 20Mbps WAN limited to 10Mbps over IPSec Tunnel
It looks like the extra 200Mhz in speed between the 750 and the 2011 hasn't made any difference to the IPSec speeds. I wish Mikrotik would publish these figures somewhere.

comment 20Mbps WAN limited to 10Mbps over IPSec Tunnel
Unfortunately not. I found some threads on the Mikrotik forums where 11Mbps was thrown around as the maximum for this router (and seems like I have confirmed this here). The blog I linked to the guy ran his tests and got around 1Mbps of traffic, but on a much, much lower powered router. Mine should be around 6-10x more powerful and I seem to be getting 6-10x the amount of IPSec traffic, which all matches up. It doesn't look like a CPU bound issue, or an IRQ bound issue, or a memory bound issue. I have no idea what's actually going on here.

@xeon bare metal host to bare metal host, no difference.

comment Need to set up domain/subdomain using NGINX
As Florin said - you need to set this up in your DNS. There is no "code" or "programming" to do this. It's a configuration option. We cannot answer how to do this because it entirely depends on where your DNS is configured.

@GregL no luck I'm afraid, same story. However I have concluded this morning that my initial tests were faulty, and it does not seem to be isolated to SMB, as with a different (more accurate) test, I can now reproduce this issue over HTTP. I've removed the HTTP red herring from my question now.

@MichelZ yes. At least I damn well hope so - Server 2012 R2 and Windows 7 at either end.

@joeqwerty that calculator is great. When I'm back in the office tomorrow I'll muck around and see what's what. Right now it looks like my total packet size is going to be 1536 bytes, which is too big.

@MichelZ I have. Tried lots of different source/destinations with the same result

comment 20Mbps WAN limited to 10Mbps over IPSec Tunnel
@joeqwerty well the problem probably did occur before the upgrade, but because it was a 10/10 link it was by coincidence capping out at the maximum available bandwidth anyway.

comment 20Mbps WAN limited to 10Mbps over IPSec Tunnel
@joeqwerty The devices at both ends of the tunnel show 0 errors, 0 pause, a handful of underruns and nothing particularly out of the ordinary anywhere else.

1394 is the largest MTU that I was able to get through.

comment 20Mbps WAN limited to 10Mbps over IPSec Tunnel
Good point. It's 9000 on both the switches at either end, 1500 on the server and clients themselves, and 1480 on the VDSL portion of the link. That's the only portions of the links that I control.

comment infiniband network between 3 servers
Which I also mentioned - chaining them off each other. Never having used infiniband I wasn't sure if that was actually possible though, but then the nodes in the middle of the ring become a "switch" anyway. Maybe not a device sitting in a rack, but they still switch packets between nodes on the network.

Not sure what was wrong about my answer? I told him that he has to use a switch in the last paragraph.

comment Practical difference between SPARC vs x86
I believe that SPARC also scales out better than x86 does. I've seen big iron SPARC machines marketed with 1024 cores at > 3GHz. Good luck getting that on x86.

comment Practical difference between SPARC vs x86
The only time I've seen sparc in the wild is in legacy systems that are on Solaris and cost too much to move to any other platform. That's also why they're so expensive - smaller market share means less demand which means a higher price.

comment SuperMicro CSE-815TQ-560B server is LOUD…can it be quieted?
The problem with 1U servers is that they need to move the same amount of heat as a 2U server, but the fans are 1/4 the size, so you need a) more of them to be at b) a higher RPM. A am surprised by your 1U server only having 4 fans - normally they'res about 6 or 8 of them. Both of these increase the volume of noise dramatically. You'll find a 2U server is much quieter, and almost bearable.

comment Stuck with Cisco DHCP pool issue
If 192.168.1.1 is a router that gets you out to the internet, then yes. I've only seen routing to an interface like you have there when it's a PPP connection, but my experience with different types of interfaces on iOS is limited.

comment GPO option for “Show Desktop Icons”?
@Daniel Yeahhhh I re-wrote his question and edited that screenshot in. I stole the screenshot by doing a google image search. The original question was a bit of a mess (see the edit history)
