PTC Creo的性能问题怎么解决

嗨，亚历克斯，
我们有几个关于CREO的案例研究是成功的，例如
佐治亚理工学院，La Cite，以及我无法命名的其他客户...没有足够的描述a）您的环境或b）实际问题猜测....
我们需要操作系统，虚拟机管理程序版本，虚拟化堆栈（XD / XA / View版本），最终客户端，RAM，CPU，每个VM的vCPU和RAM，Creo等版本的详细信息...您的部件相对于卡FB有多大（
framebuffer）等...什么是服务器等...多少K2，什么是CPU的GHz，总服务器CPU / RAM。
您是如何确定它是一个vGPU问题，如果您有一个可以消除vGPU堆栈的话，您是否可以尝试在传递中等效Quadro GPU。
你如何确定一个问题... K260Q大致类似于K4000。
最好的祝愿，
雷切尔

Hi Alex,

We have several case studies on CREO that were a success and pulic e.g. Georgia tech, La Cite, plus other customers I can't name... there isn't enough description of a) your environment or b) the actual issue to guess....

We need details of OS, hypervisor version, virtualisation stack (XD/XA/View versions), end clients, RAM, CPU, vCPUs and RAM per VM, version of Creo etc... how big are your parts relative to card FB (framebuffer) etc... what is the server etc... how many K2's, what's the GHz of the CPU, total server CPU/RAM.

How have you determined it's a vGPU issue, can you try and equivalent Quadro GPU on pass-through if you have one lying around to eliminate vGPU stack. How are you determining an issue etc... a K260Q roughly similar to a K4000.

Best wishes,
Rachel

嗨雷切尔，
抱歉迟到的回应。
我们的环境是：
Citrix XenDesktop 7.8
Nvidia K2采用K240Q型材
任何XenDesktop都有21GB RAM和8个GPU（3,50Ghz）
我们使用Citrix Provisioning Services
网格卡的驱动程序版本是：348.27
我们在Creo中使用PTC Creo Version 2和自定义设置（配置文件）
这些设置使VDI非常慢：
blended_transparency独立
skip_small_surfaces是的
edge_display_quality很高
spin_with_part_entities是的
在一个pysical Dekstop（HP Z420与K4000）工作得很好。
在其他带有AMD显卡的物理台式机上，它的效果非常好。
我们在虚拟桌面中使用我们网络中的无损压缩。
当用户来自外部（netscaler）时，我们使用H264编解码器。
但是，性能非常慢。

Hi Rachel,

sorry for the late late respons.
Our Environment is:
Citrix XenDesktop 7.8
Nvidia K2 with K240Q profile
any XenDesktop has 21GB RAM and 8 GPUs (3,50Ghz)
We use Citrix Provisioning Services
The Driver Version for the Grid Card is: 348.27

We use PTC Creo Version 2 with custom settings in Creo (config file)
these settings make the VDI very slow:
blended_transparency independent
skip_small_surfaces yes
edge_display_quality high
spin_with_part_entities yes

On a pysical Dekstop (HP Z420 with K4000) works very well.
On other pysical Desktops with an AMD graphic card it works very well to.

We use for the virutal Desktops the lossless Compression in our network.
when the user comes from external (netscaler) we use the H264 codec.

however, the performance is very slow.

嗨，亚历克斯
当你说“表现很慢”时，你能详细说明吗？
它在哪里以及如何变慢？
你看到了什么问题？
你介意给我们确认以下内容吗？
对不起，很多我很害怕的问题，还有一些让你尝试的事情：
系统
- 您使用的是哪种桌面操作系统？
- 你在运行哪个Hypervisor？
- 一般的系统性能和可用性是什么样的？
（操作系统/应用程序开放时间/数据加载时间等）
- 您的应用程序数据位于哪种存储类型？
- 您对数据有什么样的网络性能？
供应服务
- 您使用的是哪个版本的PVS？
- 它是物理的还是虚拟的？
-  PVS上的CPU和RAM是多少？
- 什么是PVS网络配置？
- 您的虚拟磁盘映像存储在哪里？
- 任何存储IO加速技术？
（Flash /缓存等）
系统硬件
- 使用3.5Ghz，您的VM CPU速度很好，没有问题。
-  K240Q配置文件只有1GB的FrameBuffer。
我很想最少使用K260Q，甚至可能是K280Q或完全Passthrough，具体取决于你的工作量。
您必须监控GPU的使用情况，并确定哪个配置文件适合您的工作负载（如果您尚未这样做）。
就FrameBuffer而言，K4000介于K260Q和K280Q / Full Passthrough之间，它是一个专用卡，与其他用户/工作负载之间共享的K2不同。
-  21GB内存有点不寻常，通常我希望看到倍数，如2,4,8,12,16,24,32等。也许这只是我以前的思维方式，但只要你有足够的
VM，然后不用担心:-)
Citrix策略
- 您是否能够准确地向我们显示正在应用的设置？
- 如果启用“允许视觉无损压缩”设置，则不是使用完全无损压缩，而是对性能非常有益。
Netscalers
- 他们是MPX，SDX还是VPX？
- 您是否针对XenDesktop / ICA工作负载进行了调整？
- 他们是哪个版本的固件？
- 在内部访问VM时，您是通过Netscalers还是直接访问Storefront？
一般
- 您是否尝试使用RDP而不是ICA来访问桌面以比较差异？
- 你进行过任何资源监测吗？
我知道这似乎相当多，但我上面提到的所有内容都会影响你的表现，所以为了有效地回答你，我们确实需要知道这一点:-)
问候
本

Hi Alex

When you say "performance is very slow", could you elaborate on that please? Where and how is it slow? What issues are you seeing?

Would you mind confirming the following for us please? Sorry, lots of questions I'm affraid, but also a few things for you to try:

System

- Which Desktop Operating System are you using?
- Which Hypervisor are you running?
- What's the general system performance and usability like? (Operating System / Application opening time / Data load time etc)
- What kind of storage is your application data located on?
- What kind of network performance do you have to your data?

Provisioning Services

- Which version of PVS are you using?
- Is it physical or virtual?
- What's your CPU and RAM on the PVS?
- What's the PVS network configuration?
- Where are your vDisk Images stored?
- Any Storage IO acceleration technologies? (Flash / Caching etc)

System Hardware

- With 3.5Ghz, your VM CPU speed is good, no issues there.

- The K240Q Profile only has 1GB of FrameBuffer. I'd be tempted to use the K260Q at a minimum, maybe even the K280Q or full Passthrough depending on your workload. You'll have to monitor the GPU for usage and decide which profile fits your workload if you haven't already done so. In terms of FrameBuffer, a K4000 is between a K260Q and K280Q / Full Passthrough, and it's a dedicated Card, unlike a K2 which is shared between other users / workloads.

- 21GB RAM is a little unusual, typically I'd expect to see multiples like 2, 4, 8, 12, 16, 24, 32 etc. Maybe that's just my old way of thinking, but as long as you have enough in the VM, then no worries :-)

Citrix Policies

- Are you able to show us exactly which settings are being applied?
- Rather than use full Lossless Compression, it is very beneficial to performance if you enable the "Allow Visually Lossless Compression" setting.

Netscalers

- Are they MPX, SDX or VPX?
- Have you tuned them for XenDesktop / ICA workloads?
- Which version of firmware are they?
- When accessing the VMs internally, do you go through the Netscalers or direct to Storefront?

General

- Have you tried accessing the desktops using RDP rather than ICA just to compare differences?
- Have you carried out any resource monitoring?

I know that seems quite a bit, but everything I've asked above can impact your performance, so in order to answer you efficiently, we do need to know that little lot :-)

Regards

Ben

嗨本，
回复晚了非常抱歉。
我们已经分析了我们的问题。
当Creo开始时，我们加载一些中心设置。
没有这个设置我们没有问题。
我们转动一些模型的表现非常好。
我们还可以看到Creo不使用graficard gpu :(

Hi Ben,
sorry for the late response.

We have analyzed witch kind of issue we have. When Creo starts we load some central settings. Without this settings we have no issues.
The performance when we turn some models is very. We can also see the Creo not use the graficard gpu :(
