Hi The image did not show. incremental checkpoint includes: 1) flush memtable to sst files; 2) checkpoint of RocksDB; 3) snapshot metadata; 4) upload needed sst files to remote, all the first three steps are in sync part, and the fourth step in async part, could you please check whether the sync or async part takes too long time. As the sync part, maybe you could checkpoint the disk performance during checkpoint, as the async part, maybe you should checkpoint the network performance and the s3 client.
