    If I killed and restart connections would be a good idea to improve performance?
  2. 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.

You might want to read 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.

NAME
Time::Human - Convert localtime() format to "speaking clock" time SYNOPSIS
use Time::Human; print "The time is now ", humanize(localtime()); DESCRIPTION
This module provides a "vague" rendering of the time into natural language; it's originally intended for text-to-speech applications and other speech-based interfaces. It's fully internationalised: if you look at the code, you'll see a global variable called %Time::Human::templates, which you can fill in for other languages. If you do multinationalise it, please send me templates for other languages to be added to future releases. You can set the default language via the global variable $Time::Human::Language $Time::Human::Evening and $Time::Human::Night decide the hours at which afternoon turns to evening and evening turns to night in your cul- ture. For instance, Greeks may want evening to start at 11pm; for hackers, evening may start at 3am. USAGE
Import Parameters This module accepts no arguments to it's "import" method (actually, it doesn't even have an import "method"). Exports This module exports a single symbols, the "humanize" function. CREDITS
