Hi,
   Based on tpch test, I have run the 10 GB data and results are attached
with this email.We see a little improvement. However,with the increase in
concurrency, the sql execution time will drop.Compared with the previous
test, it has not been improved.The block size is 1024 MB and we use your
create statement.
