Gitlab performance after upgrade

After upgrading from 7.2.0 to 7.7.2 we are experiencing alot worse performance on our server.

We are running on CentOS 6.5 using omnibus.

If I have htop running I see alot of these commands each using 100 % cpu

git pack-objects --revs --thin --stdout --progress --delta-base-offset

Our server graphs also looks a bit strange after upgrade.

Any ideas?

no ideas come to mind immediatly.
But i saw that 7.8 will have some performance optimizations.
It comes out in 4 days. Maybe the problem is already fixed. crosses fingers
