Bad performance but Low CPU loading?

There might be some problem with my server,
because every morning at 7, it's performance become bad with no DB extra deadlock.
But I just couldn't figure it out.
Please give me some advise, thanks a lot...

According to the CPU performace chart, Daily CPU loading Maximum: 42 %, Average:36%.

But I have a serious Report Delay for almost half hour.

Here is the "TOP", at the same time but the next day I collect.

Code:

Load averages: 9.60, 9.80, 6.67
682 processes: 626 sleeping, 56 running
Cpu states:
CPU LOAD USER NICE SYS IDLE BLOCK SWAIT INTR SSYS
