Ah, I see I do. Thank you Google.
It was 40 Mbps. Or around 5 MBps.
There you go
-
I then copied a 7GB file between the two VMs. That gives me a speed of around 30MBps. Nowehere near the iPerf numbers, but decently fast. (The file copied in 4 minutes.
I loaded XO on the same VMs, and tried an export of another VM. I am getting speeds of anywhere from 2MBps to 7MBps.
Clearly much slower.
-
@BRRABill Right. iPerf is testing nothing but the network. Think of it as the best you can get.

I am trying to get iPerf installed on my XS7 host. Being a Linux noob I am having some issues but working through them.
But I am assuming it is going to show the same results ... near GB speeds.

Looks like you'll have to download and install it. It's easy once you know where to download it from.
wget http://pkgs.repoforge.org/iperf/iperf-2.0.4-1.el6.rf.x86_64.rpm yum localinstall iperf-2.0.4-1.el6.rf.x86_64.rpm -

Thanks for that. It installed, but there are more issues.
I think firewall related.
But, as I said, I don't see why it would show anything other than the 1GB speeds I am expecting.
@olivier ... what did you test to show those speeds? Was it export? I think you said it was replication, right?
I'm wondering is maybe export is still just realllly slow.
Does anyone else have XS7 installed and have tested exporting yet?
-
Ive not used XS7 to do exports yet, but i have done many in 6.2 and 6.5 the last few months. Your export speed will be limited by network and source and destination disk systems.
If you have a Gb all the way, and your XS storage is fast, then you will be limited by the destination disk system. so if you have 'crappy 8 year old usb2 hdd' to export to, youre not going to be exporting at 1Gb. If you have 'new usb3 hdd' hooked up to usb3 ports on your workstation and export there, you may hit that.
I hit about 240Mbps on my exports due to using 'new usb3 hdd' hooked up to usb2 ports. Ive got a usb3 card somewhere... -
My thing is that if I copy a file from VM to VM, it is 80MBps.
If I export the same thing, it is 5MBps.
Something doesn't seem right.

I checked in on the bug tracker for this.
https://bugs.xenserver.org/browse/XSO-445Apparently this was NOT fixed in XS7.
Ugh........
-
Yikes. That one does seem to be bugging lots of people. Also nice to see someone else besides us using Jira.

We use Jira here too.

I used Jira last year, but not any longer.

As @JaredBusch would say ... FFS!
@olivier ... what have you seen that they HAVE fixed? You said replication, right? (Sorry if I asked this twice, LOL.) I don't have a second XS7 set up yet (soon) so I can't tell what that speed is like.

I started watching the bug and voted for it. Fourteen people now watching it.

And hopefully threw some traffic this way.
Good job!

This is a good place to discuss XenServer issues
-
@BRRABill Replication uses export from one XS and pipe it to the import of another one. So in any case, it's import/export.

There is no file serving or anything internally?
Sure there is, but we're talking Word and Excel files (and not million line Excel files either, usually just a few hundred KB). So we go from a second to sub-second transfers. Not sure that's worth spending money on.
But now we're beating a dead horse again because we are replacing the switches now because we want POE for VOIP phones.

OK, when I get my second XS7 stood up, I will run a test from XO and let you know.
Still, seems very strange that everything is copying perfectly EXCEPT exporting from XS, especially given all the other people with issues.
I wonder why yours is working. "What's your secret????" I ask, wanting to hurry these exports the heck up!
If anyone else has XS7 set up already, if you get some time, export a small VM and see what speeds you get.
