Thanks for sharing Mohamad.
What size of IOs are these?
The tail latency breakdown is probably a major factor of importance
here too, but I guess you don't have that. Why EC21, I assume that
isn't a config anyone uses in production...? But I suppose it does
facilitate a comparison between replica
Sorry for the delay. We used the default k=2 and m=1.

Hi,
These numbers are probably not as detailed as you'd like, but it's
something. They show the overhead of reading and/or writing to EC pools
as compared to 3x replicated pools using 1, 2, 8 and 16 threads (single
client):

Hi all,
(Sorry if this shows up twice - I got auto-unsubscribed and so first
attempt was blocked)
I'm keen to read up on some performance comparisons for replication versus
EC on HDD+SSD based setups. So far the only recent thing I've found is
Sage's Vault17 slides [1], which have a single slide
