Keeping VoIP calls up while high IP Input process cpu time
I was having a problem with a router that I'm not sure how's the best
way to prevent it from happening again. I have a MC3810 running 12.3,
and it provides a PRI and NAT through a T1 data connection.
One of the computers running through the NAT got a virus and started
opening up thousands of connections to port 443 per second. This caused
the IP Input process to max out the CPU time, and as a side effect VoIP
calls couldn't go through.
I fixed the problem with an access list so that port won't be a problem
in the future, however, I'm sure at some time so...cpu time usage of multi threaded process and single threaded process.
these are 2 programs for matrix multiplication. :-
1st one is implemented using multiple threading and 2nd using single
threading. Process' Cpu time for both comes out to be same ..... but
should be less for multi threaded process. Plzz help why Cpu time is
program1 using multiple threading :-

I have a 1989 Dell Dimension XPS T500MHz w/ 512MB RAM, running Win98. Recently, the
system has been extremely processor bound, as demonstraded by System
Monitor (Kernel Proc Usage tends to "redline"). I have been unable to
identify the culprit, but a CTL-ALT-DEL does shows tasks by the name
of "ccd", "cfd" and "mdm". When I kill these tasks (usually the are
"not responding"), the perfromance does improve. I have searched high

tasks are. They do NOT appear in the mscon...How do I get percentage CPU usage of processes for a specified time interval?
How do I get percentage CPU usage of processes for a specified time
I'm wish to write a script, part of which displays the top 10
processes by percentage processor usage over a 30 second interval. I
know "topas" can show this, but I need to be able to process the
information in a script. The output from "ps" doesn't seem to give the
Can anybody give me some pointers as to how this can be done?

I'm trying to track down what is going on with a particular rogue
application process on a customer site running AIX 4.3.3.
Under defined circumstances, the application process can be fired up and
while seemingly doing nothing will soar to the top of the topas list of jobs
whilst taking the system from largely idle to heavily CPU bound.
When this happens, it is always the kernel histogram that goes highest, and
if I time(1) the process from start to when I break it out of the resource
hogging section I get output like this:
usr:5.41 sys:19.53 total:24.94 elapsed:0m31.11s

Ever since I got my High Speed Digital Internet access from Comcast/Verizon,
my CPU runs mostly at 100% and I frequently have long (5-30 second) lockups
for no reason (sometimes coincides with changing window focus). I am
running Windows 98 and the crummy taks process program (Ctl-Alt-Del) does
not show CPU usage per-process so I can't tell what is hogging it all. Is
there a good freeware/trialware performance monitor that will show this for
W98? Anybody get Virzon/Comcast and then figure this out? Is there a
better place to post?

Scenario: new functionality was recently deployed in a 3-tier business
application. Since deployment, CPU use has shot up to very high
Using event monitors to try to track down the culprits hasn't fingered
any bad query in particular who's hogging CPU. One interesting anomaly
is that there is a single type of query that averages 70 seconds of
real time (with highs of 100-300 seconds) while expending zero seconds
of CPU. The query in question takes the form "SELECT * FROM TABLE
WHERE COLUMN = 'VALUE'" where the value is the first element in the
