Is slow performance for bulk_update normal for ORMs? #1235

No replies to any of these discussions for the entire year so I can assume this library is somewhat neglected but here goes:
Is there a way to bulk_update fields and add to what the field already is?
For example, I'm trying to recreate this query:

sql = 'UPDATE users SET timer=timer+5 WHERE online=true'

I'm trying to update all users who are online.

So far the only way I can see this being possible in Ormar is this:

users = await Users.objects.all(online=True)

Then updating everyone's timer increasing it by 5

for user in users:
    user.timer += 5
await Users.objects.bulk_update(users, columns=["timer"])

Running perf_counter this bulk_update takes almost 3 full seconds to complete. For only 60 rows I feel like this is very slow. Is there a better way to update multiple rows and increment a value more efficiently?
