It turned out that under heavy load one of the rgws have had too low soft NOFILE limit set (max number of open files). We also accidentally found that in our setup and hw the "round trips" under heavy load from frontend proxy (nginx in our case) to radosgw cost is pretty high (let us say 50% in capability of sent p/s), even if it is on the same machine and ip.
Thanks anyway. On Wed, Jul 24, 2024 at 8:25 AM Eugen Block <ebl...@nde.ag> wrote: > Hi, > > can you tell a bit more about your setup? Are RGWs and OSDs colocated > on the same servers?
