   The key evidence is still missing here. To determine whether this is a Doris 
4.1.2 regression or an environment/workload/client-side effect, we need a 
controlled comparison using the same payload size, same target table, and the 
same Stream Load parameters before and after the upgrade.
   
   Please provide the full Stream Load JSON responses for several slow labels, 
especially the timing fields such as `LoadTimeMs`, `BeginTxnTimeMs`, 
`StreamLoadPutTimeMs`, `ReceiveDataTimeMs`, `ReadDataTimeMs`, 
`WriteDataTimeMs`, and `CommitAndPublishTimeMs`. Matching BE logs for `finished 
to execute stream load` and FE logs around begin/commit/publish for those 
labels would also be very helpful.
   
   From the pasted application logs alone, the after-upgrade batches are much 
larger than the before-upgrade batches, so the current evidence does not by 
itself prove a 10x Doris write regression. It does show higher observed 
latency, especially for small Stream Load requests, but the server-side timing 
fields are needed to locate where the extra time is spent.
