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:

cpc_access

cpc_access(3CPC)														  cpc_access(3CPC)

NAME

       cpc_access - test access CPU performance counters

SYNOPSIS

       cc [ flag... ] file... -lcpc [ library... ]
       #include <libcpc.h>

       int cpc_access(void);

       Access  to  CPU	performance  counters  is  possible only on systems where the appropriate hardware exists and is correctly configured. The
       cpc_access() function must be used to determine if the hardware exists and is accessible on the platform before any of the interfaces  that
       use the counters are invoked.

       When  the hardware is available, access to the per-process counters is always allowed to the process itself, and allowed to other processes
       mediated using the existing security mechanisms of /proc.

       Upon successful completion, cpc_access() returns 0.  Otherwise, it returns -1 and sets errno to indicate the error.

       By default, two common errno values are decoded and cause the library to print  an  error  message  using  its  reporting  mechanism.   See
       cpc_seterrfn(3CPC) for a description of how this behavior can be modified.

       The cpc_access() function will fail if:

       EAGAIN	       Another process may be sampling system-wide CPU statistics.

       ENOSYS	       CPU  performance  counters are inaccessible on this machine. This error can occur when the machine supports CPU performance
		       counters, but some software components are missing. Check to see that all CPU Performance Counter packages have	been  cor-
		       rectly installed.

       See attributes(5) for descriptions of the following attributes:

       +-----------------------------+-----------------------------+
       |      ATTRIBUTE TYPE	     |	    ATTRIBUTE VALUE	   |
       +-----------------------------+-----------------------------+
       |MT-Level		     |MT-Safe			   |
       +-----------------------------+-----------------------------+
       |Interface Stability	     |Obsolete			   |
       +-----------------------------+-----------------------------+

       cpc(3CPC), cpc_open(3CPC), cpc_seterrfn(3CPC), libcpc(3LIB), proc(4), attributes(5)

       The cpc_access() function exists for binary compatibility only. Source containing this function will not compile. This function is obsolete
       and might be removed in a future release. Applications should use cpc_open(3CPC) instead.
