If I killed and restart connections would be a good idea to improve performance?
- Having one or more Filesystem backups could affect Performance too ?
Many network connections
might affect performance, but right now it isn't even established if you have "many" of them. Connections in the stated of "TIME_WAITING" will not contribute to the load at all and your suggested solution of killing and restarting connections would definitely not help at all.
Running filesystem backups
could very well degrade performance but if that is the case or not we can't say.

this little introduction to performance tuning i wrote. Most of the tools mentioned there should work for you and most of the concepts explained there should apply to your server.
I hope this helps.

RAGATOR(1) General Commands Manual RAGATOR(1)
NAME
ragator - aggregate argus(8) data file entries.
COPYRIGHT
Copyright (c) 2000-2003 QoSient. All rights reserved.
SYNOPSIS
ragator [-f ragator.conf] [raoptions]
DESCRIPTION
Ragator reads argus(8) data from an argus-file, and merges matching argus flow activity records together. In its default mode of options,
this effectively converts argus(8) files from detail to non-detail mode, and merges periodic flow report records to a single argus record,
thus compressing the argus(8) file to a reduced size.
You can modify the aggregation strategy used by ragator to merge records together, by using the -f ragator.conf option. See ragator(5) for
a complete description of the format and syntax of the flow model file.
OPTIONS
Ragator, like all ra based clients, supports a number of ra options including filtering of input argus records through a terminating filter
expression. See ra(1) for a complete description of ra options.
