Updated results are that the latest `dev` gives good latency on i3.2xlarge. we can drive that disk at 600+ mb/s. but on i3.large we can only push around 190 mb/s....
The performance profile on i3.large is very similar to that of our machines with dm-crypt enabled which appears to do its own caching that we can't control. Since i3.large uses...
In order to get nice traces remotely we'd need to ship all the debug symbols which is probably a non-starter. Once devprod starts hosting the decoding webapp the overhead of...
@ztlpn is on the case!
This performance result is from a very long time ago. Likely we still have performance impact when batches sizes reach 15MB+ but we aren't explicitly trying to optimize for this...
I haven't tried to reproduce, but I suspect that lowering our retention from 1 week to say 30 minutes may result in a reproducer. My hunch is that its not...
I suspect its going to be a challenge figuring out what is really common for on-prem since there are lots of scenarios. but all the ones mentioned so far are...
@andresaristizabal I'm looking at the ACL implementation and we already have some deduplication. I'm wondering if in your example above `alter` and `read and write` are separate ACLs but `alter`...
@mmaslankaprv did we find out about client behavior wrt multiple outstanding fetch requests? @twmb for context: we are processing fetch requests off a connection one-at-a-time. for produce requests we have...
