I have performance issues, it seems like you have changed layout showing child-tickets in a table. Jira works very poor. 
Why have you changed to table editing, it do not make the application better.

Welcome @Sara Lofdahl 

I understand your frustration, are you referring to the List view? I cannot do much to fix that issue rather ask what performance issues do you face? The rest the Atlassian product team should address.

[Sara Lofdahl]

From my perspective including the list view have impacted the response and in combination with running in a team-meeting make it intolerable. 

It could of course be something else, but from a user perspective seem linked to the list view.
