   **Requirement or improvement**
   I start use dolphinscheduler recently, but I found that , some process is 
too slow.
   I add a shell  task node content a curl test http url.
   I found that the time running the task some time too slow , the task log not 
show the progress very clear
   
   the really shell conten is 
   
   ```
   curl --connect-timeout 5 -s -I -X HEAD http://xxxxx
   ```
   
   
   log:
   ```
   [INFO] 2021-07-01 11:00:02.055  - [taskAppId=TASK-2-5149-5383]:[129] -  -> 
[/bin/bash]
        2021-07-01 11:00:01
   [INFO] 2021-07-01 11:17:47.935  - [taskAppId=TASK-2-5149-5383]:[217] - 
process has exited, execute 
path:/data/tmp/dolphinscheduler/exec/process/5/2/5149/5383, processId:26210 
,exitStatusCode:0
   ```
   it cost about 17 minutes to run this task.
   
   How to detect where the time is spend  ??
   and reduce the cost of task time  ??
