Hi, Waleed:
That is what I do everytime I reorgnized a table. The table that got
reorgnized was an IOT table with Overflow segment. After table recreated, I
move overflow segment to make it sorted.
One more thing, the table is not a key table of the applications running
on this server, thoug the table is pretty big in size.
I guess the difference in response time is from the network layer.But I
cannot prove it. No improvement in response is ok for CPU upgrade, as CPU
time is just part of the total response time, but it should not get
longer:(, right?
Thanks
Zhu Chao
