Hello,
depending on your workload, drives and OSD allocation size, using the 3+2
can be way slower than the 4+2. Maybe give it a small benchmark and try if
you see a huge difference. We had some benchmarks with such and they showed
quite ugly results in some tests. Best way to deploy EC in our fin

Hello,
what exact EC level do you use?
I can confirm, that our internal data shows a performance drop when using

can roll back to it. We haven't rerun our benchmarks on Quincy yet, but
according to some presentation it shou
