So we recently migrated from 5.1.5 to 5.7.4 confluence.
I've noticed that there is problem when saving pages that have nested macros in it.
When page is simple - without many macros - it saves normally.
But if page is with lot of structured macros, then it takes several minutes to save.
For example if I put 20 div macros in structured way (putting next macro in previous macro's body) it will take really long time to save.
How do I fix this?
