Environment
AlibabaCloud centos7
machine: 32core, 64G
A single sql mem_limit 3G
Queue max_resources: 61440 mb
I submit 10 sql to impala with impala-shell at once, I expect those 10 SQL
could run concurrently, but some of them just Queued and waitting for running
lilke this:

some sql waitting for running too long time, almost 25s.
!image-2023-07-21-11-52-25-880.png!
and this meche has enough resources to run those sql at one time:

The time difference between queued and admission completes is too high, why?
