VBR v13 GUI Performance

[RubinCompServ]

#SPLIT from System Requirements Page: Quick Survey

I think no sysadmin ever looked at a software hardware system requirements

Then they got a rude awakening when they tried to install the v13 appliance!

Agree... but you should also agree that VBR GUI / management has become a monster of slowness even on modern hardware

Always remember: we use 20% of features 80% of time. Maybe 10 / 90 with all features packed in VBR. I think Product Management should start to give an "Essentials" ISO to install just Backup / Replication and Cloud Export

Do you have all the AV Exceptions in place? I've found this to typically be the most common reason for the console feeling slow.
https://www.veeam.com/kb1999 has all of the exceptions need

If you're using Windows Defender, I wrote a blog recently about automating this - https://bcthomas.com/2026/02/automating ... xclusions/

Nice, tomorrow I'm gonna try it

VBR 13 killed GUI performance on many of my Customers Servers

Seems like the wrong thread for this...

Hi guys,

Please don’t use the “System Requirements Page: Quick Survey” topic to discuss performance issues or product requests.
I’ve moved all comments not related to the system requirements pages into a new topic.

In addition to Ben’s suggestions, have you opened a case with our support team? If performance is not as expected, it should be properly investigated.

Best regards,
Fabian

I run the script on a Customer Server, GUI / management looks faster, thanks!

The script should be a flag in VBR Setup "Do you want to make Veeam faster? Yes or Yes"

I also noticed that the GUI in v13 is way more sluggy than v12 was. Is it usind a new UI-engine?
This is not really a big deal for me, but the machine it runs on is quite fast, so I'm wondering what the reason could be.

Hi,

V13 GUI is very slow compared to V12.

What I don't get is why say "If performance is not as expected..."
How would I know what is expected or what is not expected from a new software build?

Should I always expect the new software to run that same or better than the pervious version? That's what this sounds like.

Thanks
Kevin

“Expected” means that our customers are satisfied with the performance.
If the console feels slow or unresponsive, an investigation should be started.

The cause could be related to unoptimized SQL queries or code inefficiencies introduced in the new version — issues that we can address when we have the opportunity to perform a proper investigation using logs from the customer’s environment.
However, it could also be related to the available hardware resources for Veeam Backup & Replication and the database server.

Best regards,
Fabian

Theres a script to improve GUI performance? Please tell me more. Or was it a script to setup the Antivirus Exclusions? I already did that by Hand.

[kevin.boddy]

Ok I'll log a case for your slow GUI.
What I don't understand is why your QA would not have picked this up when comparing it to V12. Surely you would do side by side testing.
Why is it left to customers to highlight these issues.

Just my two cents (to avoid this becoming a piling-on-fest), I haven't noticed any particular sluggishness in the v13 console vs. the v12 console. We did start fresh on v13 VSAs rather than upgrading our v12 Windows servers, so there could be something to "fresh small database vs. old large database", but I haven't seen a baked-in slowness at this time. Overall I've been fairly pleased that the VBR Console hasn't changed much since v12.
