You have different! While Nicolas had too much time spent in kernel 
switching threads, you spend too much time in user space ("us"):

and none in idle ("id"). Check if mysql query cache is enabled first, 
than look into output of "top" who takes most of the time: mysql or 
apache. Also look there for a total swap space and how much of swap is used.

I assume you have eacclerator installed...

Now look into my.cnf and see if have there:
concurent_insert=1

What values do you have for:
key_buffer
key_buffer_size
max_allowed_packet
max_connections
read_buffer_size
read_rnd_buffer_size
sort_buffer_size
table_cache
wait_timeout

If they are not in my.cnf, find values with SHOW VARIABLES sql.

Check if you have pconnect disabled in PHP (or typo3 install tool). This 
is important (to have it disabled)!
