Having too many connections could affect performance ?

Good evening, i need your help please

I will try to describe the scenario briefly: In a Telecom Production system application receives a certain files called CDRs(call detail records) to be processed by doing some operating systems operations and then database operations like creating indexes and uploading to a Central Database-

The applications server and database is quite obsolete OSF1 and oracle 9i.

Many times the applications turn very slow to process so performance is overheated. Of course There would be many causes for overheated performance, and it is premature to identify the problem at first glance.

So Could you tell me if below theories could affect Performance ?

I run netstat command and displays more than 102 connections some of them established state, some of them time wait, etc. So the question is having many connections could affect the performance of the application?
If I killed and restart connections would be a good idea to improve performance?
Having one or more Filesystem backups could affect Performance too ?

I appreciate your answers in advanced or if u have any other reason that could impact its performance let me know. Thanks

mrtg2pcp

MRTG2PCP(1)						       Performance Co-Pilot						       MRTG2PCP(1)

NAME

       mrtg2pcp - Import mrtg data and create a PCP archive

SYNOPSIS

       mrtg2pcp hostname devname timezone infile outfile

DESCRIPTION

       mrtg2pcp is intended to read an MRTG log file as created by mrtg(1) and translate this into a Performance Co-Pilot (PCP) archive with the
       basename outfile.  The hostname, devname, and timezone arguments specify information about the system for which the statistics were
       gathered.

       The resultant PCP achive may be used with all the PCP client tools to graph subsets of the data using pmchart(1), perform data reduction
       and reporting, filter with the PCP inference engine pmie(1), etc.

       A series of physical files will be created with the prefix outfile.  These are outfile.0 (the performance data), outfile.meta (the metadata
       that describes the performance data) and outfile.index (a temporal index to improve efficiency of replay operations for the archive).  If
       any of these files exists already, then mrtg2pcp will not overwrite them and will exit with an error message of the form

       __pmLogNewFile: "blah.0" already exists, not over-written

       mrtg2pcp is a Perl script that uses the PCP::LogImport Perl wrapper around the PCP libpcp_import library, and as such could be used as an
       example to develop new tools to import other types of performance data and create PCP archives.
