Hi,
I would like to make a request to members on getting tips on the following:
We would like to know how to make CLONING (the OS) from one Linux server to
another server (without reinstallation).
Can someone help us to achieve this?
Best Regards,

Hello folks ,
I need some inputs or guidance on improving the performance of existing
c/c++ code on Linux .
Places to look for improving the performance in terms of cpu /network/
and i/o inside the code.
I would like to any guidelines to collect information for the application
resource usage/netwok and i/o metrices
please let me know do we have guidelines , tools to identify these kind of
improvements inside the c/c++ code .
any tools or guidelines will be helpful
i have used vmstat/netstat/iostat for whole system but i need on
application basis .
It is about coding boss, not tools. ;)

You can use profiling tools like GProf, OProfiler, etc..

how to check correct bandwidth usage and how to stop automatic

what to do for that?
You could try Gkrellm for bandwidth monitoring. If you're fine with
CLI, see

Thanks mehul, gkrellm has week & month wise usage log for
bandwidth..it will be useful to me:)

Hi,
Good to hear that you got your broadband connection. But
unfortunately, the link that BSNL gives works only with Internet Explorer.
:-( But I think you can use Wireshark to analyze your network usage. Or else
you can try creating a shell script. Be careful with torrents though!
gkrellm came handy to me for bandwidth usage.. thanks for your info.

You mean perhaps tcpdump, nmap et. al. right? and a custom time
measurement wrapper for your app?
localhost can be your benchmark host.
(with perhaps the most comfortable performance zone for typical
business app dev junkie)
Preferably send the data our wire and measure the wirespeed and base
your metrics on that. Including SAN if any. (storage Area _network_
right?)
man start with some php-app end-to-end performance tuning. Whew!
