Thank's Eric, I understand.

But if configuring a load balancer I'm adding another hop with reducing the performance, seems that is not the best way to improve this performance, correct?

As I explained before, it's only a test setup before move to a real environment.

Now I have a single server (8 cores, 32GB RAM with prefork) and the following apache tunning. In some moments, I have thousands of concurrent connections that collapse the server and I thought the best way to fix this was by setting up a load balancer. Isn't it?

ServerLimit 800
StartServers 10
MinSpareServers 200
MaxSpareServers 400
MaxRequestsWorkers 800
MaxConnectionsPerChild 10000

"load balancer" is an overloaded term. 

A HTTP reverse proxy is one way to scale to multiple servers. There are ways that are lighter weight at runtime like a VIP or NAT forwarding.

But it may be moot for your real workload.
