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

newproc.d

newproc.d(1m)							   USER COMMANDS						     newproc.d(1m)

NAME

       newproc.d - snoop new processes. Uses DTrace.

SYNOPSIS

       newproc.d

DESCRIPTION

       newproc.d is a DTrace OneLiner to snoop new processes as they are run.  The argument listing is printed.

       This is useful to identify short lived processes that are usually difficult to spot using traditional tools.

       Docs/oneliners.txt and Docs/Examples/oneliners_examples.txt in the DTraceToolkit contain this as a oneliner that can be cut-n-paste to run.

       Since this uses DTrace, only users with root privileges can run this command.

EXAMPLES

       This prints new processes until Ctrl-C is hit.
	      # newproc.d

FIELDS

       CPU    The CPU that recieved the event

       ID     A DTrace probe ID for the event

       FUNCTION:NAME
	      The DTrace probe name for the event

       remaining fields
	      These contains the argument listing for the new process

DOCUMENTATION

       See the DTraceToolkit for further documentation under the Docs directory. The DTraceToolkit docs may include full worked examples with ver-
       bose descriptions explaining the output.

EXIT

       newproc.d will run forever until Ctrl-C is hit.
