App loading really slow (more than 2000 rows)

[efeewfew]

Hey there! 

I got a sharepoint list with over 2000 rows, so I am using the clearcollect trick to get access to all rows (about 6000)

But it is loading extremely slow (about 10 seconds). Is there any way I can make this code even faster?

Concurrent
(
    ClearCollect(col1; Filter('D-Nummers-OpleverApp'; UniekID >= 1 && UniekID <= 2000));
    ClearCollect(col2; Filter('D-Nummers-OpleverApp'; UniekID >= 2001 && UniekID <= 4000));
    ClearCollect(col3; Filter('D-Nummers-OpleverApp'; UniekID >= 4001 && UniekID <= 6000));
    ClearCollect(col4; Filter('D-Nummers-OpleverApp'; UniekID >= 6001 && UniekID <= 8000));
    ClearCollect(col5; Filter('D-Nummers-OpleverApp'; UniekID >= 8001 && UniekID <= 10000))
);;
ClearCollect(colCombined; col1; col2; col3; col4; col5);;

Concurrent(
    Set(gblUser;User().Email);;
    ClearCollect(ColAdminsOpleverapp;Admins.AdminsOpleverapp);
    Set(deelorderChosen;"0");
    Set(DateChosenYesNo; "")
);;

Concurrent(
Set(bedrijfNaam; LookUp(MontageBedrijven; gblUser = Email; MontageBedrijf));
Set(IsAdmin; !IsBlankOrError( LookUp(ColAdminsOpleverapp;AdminsOpleverapp = gblUser)))
)

Thanks in advance!

I don't think that it is a faster way to do that.

I think the 'problem' is that you have a lot of data and it will become slower, it is normal.

My only advice is for you to replace the "colCombined" and use directly your data source ('D-Nummers-OpLeverApp) and in your galleries filter it very well (you can do a sort of pagination).

It is up to you

Thank you for your reply @Nogueira1306 

But it is simply not possible to filter it back down so it gets below 2000 rows. This is a list of all of the projects, which are all needed to be loaded

HI @efeewfew ,

I am not sure whether this will be faster, but you can try it

Clear(colCombined);
With(
   {
      wSets: 
      With(
         {
            wLimits: 
            With(
               {
                  wLimit: 
                  Sort(
                     'D-Nummers-OpleverApp',
                     UniekID,
                     Descending
                  )
               },
               RoundDown(
                  First(wLimit).UniekID / 2000,
                  0
               ) + 1
            )
         },
         AddColumns(
            RenameColumns(
               Sequence(
                  wLimits,
                  0,
                  2000
               ),
               "Value",
               "LowID"
            ),
            "HighID",
            LowID + 2000
         )
      )
   },
   ForAll(
      wSets As MaxMin,
      Collect(
         colCombined,
         Filter(
            'D-Nummers-OpleverApp',
            UniekID > MaxMin.LowID && UniekID <= MaxMin.HighID
         )
      )
   )
)
