Public bug reported:

Hello,

I faced the issue with many2many_tags widget, there is issue of
performance due to series of name_get calls, when there is a
many2many_tags widget in list view.

Steps to produce: Create a 80 to 90 records in a listview where there is
a many2many_tags widget available, say for example take a Sale Order
Line create 80 to 90 records for Sale Order Line, after creation just
open or edit that Sale Order record you will notice many2many_tags takes
time to load, you will also see record is loading...

The reason is simply design of many2many_tags, many2many field calls
name_get for each record of sale order line, so if there are 80 records
in list then 80 name_get calls goes to fetch name for many2many_tags and
it creates performance issue.

For now I do not have any solution suggestion from web-client because
when we edit or Save the record record is reloaded by design, I am not
sure but it should be fixed from server same as many2one sends return
value in format (id, value), we should return value for many2many field
in format [(id, value), (ids, value)...], I am not sure this is the only
way but I think this way name_get will not be needed anymore after this,
we also need to change the many2many and many2many_tags widget to deal
with such values.

Thanks.
