New workstation 5x as slow as old one.

We bought the first of 10 new workstations to find out it is 5x slower than the old ones. 

 

The new workstation is a Hp Z4 G4 with a Xeon W-2225, 32Gb Ram, P2200, and 512GB SSD. We are testing it with our company template file, which opens in 12 sec on our old workstations and take up to 52 seconds on the new one.

 

Now hardware isn't the issue, when running the Hp Performance Advisor we don't hit any limits. CPU is nicely boosting up to 4.6Ghz and does an average load of 30% over the cores. None of the cores hit 100%. The workstation is even faster (as expected) when running benchmarks.

 

So after a lot of other tests, we started taking a close look into the journal files and I noticed one thing:

 

 

 

'C 15-Sep-2020 08:00:46.223;  LoadLatestEpoch::loadLatestEpoch 0x00007658f3c=thelper.currentPos() 0x00007659fa7=thelper.targetPos()

' 44.963442       5:<<TrustedUtility::readStreams 
' 5:< class RbsSystemPropagationFilter adding (AtomFinish, -1) to allow propagation to PanelScheduleView 

 

 

 

This is a part of the journal while opening the template file. Between the two actions is 26 seconds. Every time a step takes longer than a couple of ms in the log, I see a line Delta VM: Avail. It seems to output the performance stats, but what is it or what does it indicate?

 

I have attached the complete journal. Anyone an idea why it's so slow?

Since this is a new PC, I'd be trying to attack this from another front.

The hardware or drivers may be an issue here. And on a new PC with a wiz-bang video card, the drivers can often cause issues when the video card is still in an early stage of its life-cycle.

Getting all the drivers up to date is a good start. Find out the exact model of the video card and go to the vendor's website to download the latest build of the drivers. Windows Control Panel > Hardware cannot be relied upon to tell you is your drivers are truly the latest version.

The issue is that doing a truly exhaustive search on hardware issues can a lengthy process but a quick(ish) test is to see if the RAM is OK - it can be an issue and this freeware app' can tell you if there is a problem - https://www.memtest86.com/

 

Insert witty comment here.

We checked the RAM modules this morning by swamping them out. I just re-installed the machine (formatted, re-installed Win 10 and Revit 2021) and it's now running as expected.

 

I didn't format it when we received the workstation, so there was some Hp software on it, like Hp Sure Sence (which I had disabled), but maybe something else caused the problems.

 

So for now the problem seems to be solved.
