well, you may want to :
run faster hardware
re-code your CGIs in a faster/compiled language
desactivate every apache module that are not absolutely compulsory
set "allooveride" to None everywhere in your httpd.conf
limit the number of httpd spawns to a smaller number so that the machine
does not lose time forking new processes and use this time to execute
CGIs faster
these are just ideas

How to decrease the load? Well, from the statistics you posted, and
given that all the CGIs etc. do legitimate things, you need a faster
server (more CPU power) and/or multiple servers with load balancing, the
latter provided that the applications you run there are suited for load
balancing.

If you're really getting enough traffic to explain this many concurrent
processes, then you should be celebrating, and buying more hardware.
If there's not really that much traffic, then you need to find some way
to re-design your CGI programs to spawn fewer processes.

加服务器，其他服务是什么?

很难有解决办法，除非升级服务器，特别是内存
