On that note, I'm going to the nearest bottle.

@dafyre Both ( default server card)

As I'm running Crystal Disk Mark the speeds are so horrible I want to vomit.

Can't be the NIC (???) I'm doing like a file transfer from one folder to another on the same disk/vm of the vm that I'm running. When I tried last night to copy vm to vm yea after 10 hours only 1/3rd got done give or take an hour or so.

Potential bad switch as in maybe one of the interfaces is bad? I think a long time ago me and scott thought about switching to 10 gb interconnects for each switch

@scottalanmiller can't be it, because sometimes I see it do 60 Mbps + like during OS install or if I happen to catch it.

ook at the NIC status, what does it show the connected speed?

1 Gb

I'll probably wait till everyone leaves and come in the morning early to double-check the BIOS. The disabling of the VMQ however, when I ran the command it didn't return that I had anything enabled....

I checked the Xen nic, and it doesn't have a listing in the advanced tab for the VMQ

@black3dynamite not yet, I can try that again but I think my nic's are intel (not 100% sure), this is what I have done so far.

https://docs.microsoft.com/en-us/windows-server/storage/file-server/troubleshoot/slow-file-transfer

Keep in mind I've had same issue on EVERY hypervisor from Citrix, VMWare and Hyper-V. I know hyper-v has its flags you need to turn off that are clearly documented to address the situation it has with nic's but were talking on the same SR lol. Not transferring across nic.

Also it can't be the vm setup because it's the same performance whether on 2-core, 4-core, 8-core, with ram up to 16 Gbs. So if it is vm level, I'm happy to check whatever anyone suggests.

For clarity, last night I kicked off a 1.5 TB file copy and when I woke up on 500 Gb in change was transferred after 9 hours. -_-

So I read an article from a senior level virtualization expert on the Dell BIOS system performance setting. Could be that but I don't have the ability to check right now. At home in my lab when I noticed that some of my vm's were going crap after about 10 of them were running, I properly enabled the settings and that fixed the issue of some of the sluggishness at my lab. Keep in mind this is an old R710 with a 512 Mb H700 with 2 drives in a raid 0. Not really a good comparison.

Honestly, every system I've virtualized ever has had the same issue with windows slow as hell file transfers.

Yes I use the local SR. At work, unfortunately, I used thin provisioning and will be switching back to thick when I do updates.

Can't be the drivers (this time) as they were always installed properly. I have taken some time to "bork" one system in my lab. It's nigh impossible to fix when the drivers are screwed up.

The system I'm currently on are two R530's both on RAID 10 with 4 drives (8 total but not using the other 4 yet). Dell brand drives I don't remember speed but assume they are NL-SAS with either 7200 RPM or 10k RPM.

Why in the hell can I not get better speeds? It does this on every host I have. I have an all ssd host, does the same thing....

@scottalanmiller my two orders got through and will be shipped 3 weeks ahead of time.

@Dashrender all ubnt

@Dashrender i would need pretty detailed help on that (key thing is I’m not a network engineer)

Off top I can think of a few options to help remove the dependence of Excel. This is a short list.

Microsoft Power Apps
Google App maker
Quickbase
Zoho Creator

@Dashrender i use ITarian it’s free. There are other tools specific to Apple that can be free also that basically do the same thing.
