[data grid] Performance: data grid spends about half the time sorting and filtering even though the features are disabled

[scamden]

Steps to reproduce

Link to live example: https://codesandbox.io/p/sandbox/datagrid-huge-tree-shared-with-mui-forked-lf9gz3

Steps:

1. Start perf trace
2. Mount the grid
3. Sto the trace

Current behavior

About half the time is spent filtering and sorting despite it being disabled

Expected behavior

no time is spent sorting or filtering when it's disabled

Context

Increase performance on a very large data grid

Thanks @scamden for reporting this ... I have put it on our board for the team to have a look!

The disableXxxx flags aren't meant to fully disable a feature, they fullfill the same role as the input[disabled] attribute: the feature is UI disabled only, but still present. All the grid flags are going to be UI-disable only, this is being clarified in v7.

However, we should be able to avoid the performance cost in some cases.

For filtering, we can avoid filtering if:

• Filtering mode is "client"
• Filter model items is empty
• Filter model quickValues is empty

One issue we have though is that we create a filteredRowsLookup which has the structure { [id: GridRowId]: boolean | undefined }, and we set the value to true for all rows. So we have a cost that scales as O(n). Some of this could be avoided by the work in #10068 I think. We should probably also have a special Set value that allows us to encode "everything" without having to explicitly set each value, it would save runtime & memory costs. Something like this:

enum RowSet {
  All,
  Some(Set<GridRowId>)
}

For sorting, I have no idea what can be done, I haven't touched that part of the codebase yet.
