I guess disabling batching makes sense since backlog is counted in entries.
to further reduce the test time, it would be possible to also adjust the
config of `managedLedgerCursorBackloggedThreshold` since less messages would be
required to reproduce the issue.
```
@Override
protected void doInitConf() throws Exception {
super.doInitConf();
this.conf.setManagedLedgerCursorBackloggedThreshold(10);
}
```
