VMware View + PCOIP HostCard

[Herb0ne]

Hi guys,

I'm using a pcoip hostcard from evga - the hd02- in combination with a vmware vew connection server. It all works perfect the only thing is that the performance is very poor. I cant do 3D intensive things because it lags so much. The fps are goot(no wonder cause of the powerfull pc with host card), but I think I've some bottleneck because of my lan bandwith. I'm currently using a di-524 router which connects the vm-server and the pool pc and the client pc. It has a Bandwith of 100Mbit. Do you think switching the router to an 1Gb would do the trick?

That's quite possible.

Personally, I'd first look at the Session Statistics in the host card's Web Interface.

On what value I've to take a closer look? Sorry but I'm quiet new to this kind of stuff :smileylaugh:

[MarAndreas]

The big one is the Bandwidth Limit - if that's set too low, changing the network hardware won't make any difference, because the card won't even try to use it.

Second is the Bandwith Maximum - if the 100MBit router is the bottleneck, and if it actually provides as much bandwidth as it's supposed to, this should get close to 100MBit.

(Note that the page shows the current session, so you have to put some load on it to get a meaningful number)

I did a quick Sanity Check of sorts with a zero client (I have no host card available, unfortunately)

When configured for a 10MBit connection, its Receive Bandwidth Max topped out at 3024 kbps

Normally, it's somewhere around 4500

On a 100MBit connection, I could push it up to 20160 kbps, but I think that's due to the load I could put on it, not the network.

I also noticed that the Bandwidth Limit display on the statistics page is a dynamic limit - to see the actual configured limit, you have to check the Configuration -> Bandwidth page

[Herb0ne]

Do you know where I can change the bandwidth value? I think I've to change theese values somwhere in the vmware environment. I know that I can change the limit for the hostcard called Device Bandwidth Limit, but this is allready set to 0 = no Limit. But when I apply some load(running a game) the bandwidth limit won't go up. Here are some screenshots:

My settings:

My Session:

Just for completeness, I've a 1Gbit switch now which connects all components.

[MarAndreas]

No, I don't know any setting in View that would influence that.

But from what I've seen today, the "Limit" on the statistics page isn't really acting like a limit - any time traffic got anywhere close to reaching it, the "Limit" increased.

The bandwidth you're actually using is well below what I saw on a 100MBit link, and I'm pretty sure I had a CPU bottleneck.

But the Packet Loss looks worrying - I can't remember ever seeing that reach double digits, let alone exceed 100.

It all looks healthy, except the packet loss rate.

More bandwidth will not help. You have a maximum usage of 13 Mb/s, which is at the rate of a good HDTV transmission. We had made 3D-CAD on a 50 Mb-line with 50 users.

You should isolate, if you have a line problem.

Second question : is the traffic tunneled through your connection server ? Maybe there is a bottleneck ?
