Hi,
I think there are a couple of potential explanations for the increased latency.
Let me point out two of the most obvious that come to my mind:
1) A state size of 20 MB sounds like something that could (completely or to a
large extend) fit into some cache layer of a modern CPU, whereas 200

We have also faced similar issues. The only thing that happens in sync when
using async snaphots is getting a persistent point in time picture which in
case of rocksdb backend is making symlinks
We have also faced similar issues. The only thing that happens in sync when
using async snaphots is getting a persistent point in time picture which in
case of rocksdb backend is making symlinks. That would linearly increase
with number of files to symlink but this should be negligible. We could
Hi all,
In our application we have a requirement to very low latency, preferably less
than 5ms.
We were able to achieve this so far, but when we start increasing the state
size, we see distinctive decrease in latency.
We have added MinPauseBetweenCheckpoints, and are using async snapshots.
