Citrix Storefront - Performance Testing and Tuning - Part 4 - PerfMon Counters, PNA Logon

02 Jun 2017

In looking at the performance of the Citrix Storefront Server, one of the thing I want is to understand what Storefront is doing at each stage of a session life cycle. There are two session-types that I”m curious about, a web browser based connection and a PNA connection. I”m going to examine a PNA based connection in this post. See this post for a browser based examination.

Using my powershell script to simulate a user connection I put “pauses” between each stage. I then setup Perfmon to capture counters from the following objects:

I’ve added 6 farms to the storefront server to examine the load in a real world environment as Storefront does do some magic with concurrent enumeration. What I love that Citrix has done, is actually time the transactions AND gives you the “rate” the transactions are occurring at. This will make it much easier to baseline what your load is vs how I had to do it to measure the “rates” for Web Interface.

$stage = “Client Configuration”

$store + “config.xml”

So for a web browser based connection, I “connected” to the site and saw nothing in the perf counters. Storefront does very little work for the initial connection.

$stage = “PRELAUNCH”

$store + “enum.aspx”

I do not have any PRELAUNCH applications.

However, we do get perfmon counter data with this request:

This launch only hits the specific XML service from Storefront now:

Citrix Delegated Explicit Authentication\Authenticate Average Time (Microseconds) : 88,206

Citrix Xml Service Communication(XenApp65t.bottheory.local)\Network Traffic Average Time (Microseconds) : 142,010

Final results:

When PNA is used, it makes POST commands to the Storefront web services that then forwards those requests to the XML brokers, compiles the results and sends them back. It’s pretty obvious that the performance of the brokers is imperative for PNA to operate efficiently.

I kind of wish Storefront would break down the XML perfmon requests into their sub categories. By averaging out all requests to the XML brokers, it would make it difficult to pinpoint which sequence of events may be causing your pain point. The values will allow to target a specific XML broker for further analysis, but some it could have been further helpful if you knew specifically that the “&5.bottheory.local” broker was 10x longer to enumerate your full application icon list. An average could ‘hide’ that bottleneck. My account has over 400 published applications and gets 100 different individual icon requests after the ‘icon-all’ request. If this counter truly measures the average it would obscure the high ‘icon-all’ time as 100 instances of would outweigh the single metric.

However, this is still fantastic information. I have written a couple scripts for ‘querying’ each stage to measure the response time of Storefront/Web Interface and Citrix has effectively added the ability to just pull that information from real users using these counters! It’s now easier and more important than ever to monitor your XML brokers from Storefront to ensure you are running at optimal efficiency.

To put these counters in context, the ‘Network Traffic Calls / second’ and ‘Network Traffic Calls / Total’ will tell you which of your XML brokers are getting hit the most. The Total will give you that big picture, “this guy gets hit alot” and the per second counter will give you that real time data.

The “Network Average Time” will give you the data on how long or how hard that particular broker is working. The higher the number the more work it’s doing or the more you should focus on optimizing it. I don’t have a guide for what these numbers should be, as different users will have different expectations. But I have shown what the values we get and I would argue we get great performance so I would try to keep your numbers below mine
