[MM3-users] Re: Slow performance when listing members on Postorius

We have further experimented by adding the field "_member_id" in the table member as one of the keys. Before adding, listing 25 members in a page takes around 16 seconds. After adding, it takes less than 1 second. There are more than 650000 records in the table member in our testing installation.

Is it safe to add "_member_id" as key as a workaround if we want to fix the issue in 1.3.10? Will we also consider to add it as key in future releases if there are no negative impacts?
