version 18 is too slow compared to version 17, not usable for me

No, this is a specific problem in the Selector tool.
Have the issues with large documents and repeating objects been reported elsewhere? What is the scenario?

I swear I bashed my gums over this with Xara (& Cloud) back in July last year.
I was no willing to upload a 56MB files during the middle of a frustrating development period.

My workaround was to delete all Repeating Group while working on the design and re-apply prior to a re-issue.
My second workaround was to fall back to XWDPv15.0 as my client had that and reported fewer timing problems.

Basically, the selection of any shape would freeze the application for 15+ seconds.
The MS Windows Ring of Ouroboros would spin for 15+ seconds; the Web Properties > Link > Link to box would vanish; the monitor screen would go black; the application would jump behind other open windows.
Each and every click.

I have cut out all the large images and the file size is now 3MB. The document has 107 web pages and one Variant.
In Xara Pro+ (Xara Designer Pro+ 21.0.0.61527 SL x64 Mar 9 2021), the same is still occurring. [Pro+ is referred to as Xara Designer Pro+ 18 18.0.0.61527 in File > Document History > History tab]

UPDATE: I tried a PM with Attachment but lost it - I will email your directly.

UPDATED UPDATE: I have just created a test file that all can play with: Repeating Groups FAIL.xar
The delay in this simply Conventional Website is around 3 seconds a click, a move, a jump. same applied - 3 seconds - for a single letter change in the text!
Open the Web Properties dialog and watch the Link Tab and the Link to Box.

Consider the frustration when this telescopes out to 15+ seconds.
