RTC Performance - Pages opening slow all over

bbrown

We have a site that has started reporting intermittent performance issues with Role Tailored clients. So far I see nothing that leads me to think this is a SQL performance issue. That's why I did not post in that specific forum. This was brought to my attention late last night. So my information may be somewhat limited at this time. I will post more information as I get it. Feel free to post questions. I'm just looking for ideas and direction in resolving these issues.

The problem has been reported as "...pages open slow...". To clarify I have asked "Is it just the opening that’s slow? How well do they perform once opened? For example, once the Sales Order page is opened, does the process of creating/selecting a sales order proceed with acceptable speed?"

Here's some information on the RTC infrastructure:

The servers are virtual.

There are roughly 100 RTC users.

All RTC users run NAV via RDP sessions.

The RDP sessions are hosted by a NLB server farm consisting of 5 dedicated servers. Each server has 32 GB memory.

There are 5 RTC services. Each service runs on its own dedicated Windows server. The users are distributed fairly evenly across the services.

We did increase the MetadataProviderCacheSize from 150 to 5000 as noted in some blogs.

What is the CPU usage on all the servers?

Good question. I don't have that information yet. I'll see if I can get it. This is in the early stages of information gathering. Mainly with emails late last night reporting the issue from the project team. The client is 3 timezones west of me. So addtional info is just starting to come in. I will post new relevant info has it is available.

While there are a good number of users, this is also a brand new site with a tiny little database.

Updated information seems to be pointing to the Remote Desktop servers as the point of the problem. But investigating further. They setup a couple direct users (no RDP) and so far they seem to run fine.

I'm still waiting on the CPU data.

If its intermittent then check to see if the terminal server is installing anything at the time (e.g. Windows updates) - I've found that this can sometimes hog the CPU and cause performance issues.

Had the same problem. It was caused by Jet Reports. They have since released a patch to address this though.
