Efficient logging of time measurements
Hi all,
I am working on a software, which was developed using C programming on unix environment. I have added certain functionality to the software.
Now, I interested in measuring time taken by new functionality (Mean value of huge amount of tests). Since new function will be part of many threads and will be running simultaneously.
I am looking for a efficient logging mechanism to log time duration for each execution, that will not reduce the performance.
I hope appending to a log file creates bottleneck.
FYI. This software is real time one and will be running for many weeks.
Thanks in advance,
Tamil

I'm using korn shell to connect to oracle, retrieve certain values, put them in a list, and iterate through them. While this method works, I can't help but think there is an easier method.
If you know of one, please suggest a shorter, more efficient method.

device::modem::log::file
Device::Modem::Log::File(3pm) User Contributed Perl Documentation Device::Modem::Log::File(3pm)
NAME
Device::Modem::Log::File - Text files logging plugin for Device::Modem class
SYNOPSIS
use Device::Modem;
my $box = Device::Modem->new( log => 'file', ... );
my $box = Device::Modem->new( log => 'file,name=/var/log/mymodem.log', ... );
...
DESCRIPTION
This is meant for an example log class to be hooked to "Device::Modem" to provide one's favourite logging mechanism. You just have to
implement your own "new()", "write()" and "close()" methods.
Default text file is "/var/log/modem.log". On Windows platforms, this goes into "%WINBOOTDIR%/temp/modem.log". By default, if the folder of
the log file does not exist, it is created.
This class is loaded automatically by "Device::Modem" class when an object is instantiated, and it is the default logging mechanism for
"Device::Modem" class.
Normally, you should not need to use this class directly, because there are many other zillions of modules that do logging better than
this.
Also, it should be pondered whether to replace "Device::Modem::Log::File" and mates with those better classes in a somewhat distant future.
REQUIRES
Device::Modem
EXPORTS
None
