These performance problems are really strange, you server should easily 
be able to handle the traffic. It seems like your apache is already not 
performing, so maybe it is not even a TYPO3 problem...

You gave a lot of not-so useful info, please provide the following:

1. The output of an ab -c 100 -n 1000 of some static file in your 
website (the logo picture, or whatever), preferably when the server is 
idle (at night?)

2. The same output for retrieving theindex.php of your website, so we 
measure TYPO3 performance.

I tried to do it from here, and the numbers are really low (36 req/s for 
a static file, which is ridicolous), so I suspect your server is 
severely misbehaving. But since I'm in another net, and it may be heavy 
traffic time on your server, the numbers may be biased...

I don't want to blow my own trumpet, but see also
