Sudden drop in performance between 1.2.3 and 1.2.4 about react-native-largelist HOT 3 CLOSED

I looked at the log.

Yes, you are right. 1.2.4 takes more time when initializing by default for the 2 reasons:

• The default numberOfCellPoolSize increased to prevent it from appearing blank.

• Render more unused items when initializing to prevent it from appearing blank.

To solve your problem , you can set the numberOfCellPoolSize and safeMargin smaller. I suggest you set it to

(large list visible height + 2 * safeMargin)/min Cell height

Of course， you can set it smaller to initialize faster . But if it is too small ,it will not work well. You can try it.

Notice：

LargeList does not create cell when sliding, they are reused.

If numberOfCellPoolSize is too large, it takes more time when initialing and reloadData.

If it is too small, LargeList will not work well.

If you set safeMargin smaller, do not forget that dynamicMargin must be smaller than safeMargin

Then the trick is finding the right setting, I take it
