You can optimize ceph-osd for this of course. It would benefit people
that like to use the 1Gbit connections. I can understand putting time
into it now does not make sense because of the availability of 10Gbit.
However, I do not get why this was not optimized already 5 or 10 years
ago.

This is a natural condition of bonding, it has little to do with
ceph-osd.
Make sure your hash policy is set appropriatelly, so that you even have
a chance of using both links.

The larger the set of destinations, the more likely you are to spread
traffic across both links.
Osd's do not even use bonding effenciently. If it
were to use 2 links
concurrently it would be a lot better.

Hi Philipp,
More nodes is better, more availability, more CPU and more RAM. But,
I'm agree that your 1GbE link will be most limiting factor, especially
if there are some SSDs. I suggest you upgrade your
networking to 10GbE
(or 25GbE since it will cost you nearly same with
10GbE). Upgrading
your networking is better than using bonding since bonding cannot have
100% of total links bandwidth.
Best regards,
