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
