Saving slow with many Replicator fields / big entries

[jonassiewertsen]

Bug description

We noticed that our time to save entries multiplied on big entries, with many replicator fields and lots of data.

It took about 1 - 2 seconds before the update. After updating, the time increased to 5 - 10 seconds.

The performance bottleneck comes with #6842

I saw the PR https://github.com/statamic/cms/pull/8712/files in the upcoming version 4.20.0, but in our case we reverted 6842 only as we don't use any Events and the performance is as expected again.

How to reproduce

1. Create big entries with many replicator fields and lots of data.
2. Press save

In your tests, was it the PHP side that is slower, or the JS?

[jonassiewertsen]

The PHP Side.

We did only measure on save itself, after an entry has been opened already.
