HarmonyOS 数据库插入15000条数据，耗时近9s，有没有更高效的插入方法呢？

async executeInsert(conflictResolution?: relationalStore.ConflictResolution): Promise<number> { 
  let listener = this.standardDatabase.getTableChangedListener(); 
  if (conflictResolution) { 
    return this.db.insert(this.tableName, this.valueBucket, conflictResolution).then((data) => { 
      if (listener != null) { 
        listener.onTableChanged(data, TableAction.INSERT); 
      } 
      return data; 
    }) 
  } else { 
  return this.db.insert(this.tableName, this.valueBucket, this.conflictResolution).then((data) => { 
  if (listener != null) { 
  listener.onTableChanged(data, TableAction.INSERT); 
} 
return data; 
}) 
} 
 
}
