Question How can I solve this problem?

I'm now designing a server application which can serve large number of clients' request. I've a question to ask, that is, main process will block when invoke the "accept" function, if a client request comes, main process should be separated into 2 processes by invoking "fork" function, the parent goes on with accept function, the child to serve the connected client's request. My question is, if there are large number of clients want to get connected with the server, the server application should be forked many times, is this harmful to our server resources?

Net::Server::Fork(3)					User Contributed Perl Documentation				      Net::Server::Fork(3)

NAME
Net::Server::Fork - Net::Server personality SYNOPSIS
use base qw(Net::Server::Fork); sub process_request { #...code... } __PACKAGE__->run(); DESCRIPTION
Please read the pod on Net::Server first. This module is a personality, or extension, or sub class, of the Net::Server module. This personality binds to one or more ports and then waits for a client connection. When a connection is received, the server forks a child. The child handles the request and then closes. With the exception of parent/child signaling, this module will work (with basic functionality) on Win32 systems. ARGUMENTS
check_for_dead Number of seconds to wait before looking for dead children. This only takes place if the maximum number of child processes (max_servers) has been reached. Default is 60 seconds. max_servers The maximum number of children to fork. The server will not accept connections until there are free children. Default is 256 children. max_dequeue The maximum number of dequeue processes to start. If a value of zero or undef is given, no dequeue processes will be started. The number of running dequeue processes will be checked by the check_for_dead variable. check_for_dequeue Seconds to wait before forking off a dequeue process. It is intended to use the dequeue process to take care of items such as mail queues. If a value of undef is given, no dequeue processes will be started. CONFIGURATION FILE
See Net::Server. PROCESS FLOW
Process flow follows Net::Server until the post_accept phase. At this point a child is forked. The parent is immediately able to wait for another request. The child handles the request and then exits. HOOKS
The Fork server has the following hooks in addition to the hooks provided by the Net::Server base class. See Net::Server "$self->pre_accept_hook()" This hook occurs just before the accept is called. "$self->post_accept_hook()" This hook occurs in the child after the accept and fork. "$self->run_dequeue()" This hook only gets called in conjunction with the check_for_dequeue setting. HOT DEPLOY
Since version 2.000, the Fork server has accepted the TTIN and TTOU signals. When a TTIN is received, the max_servers is increased by 1. If a TTOU signal is received the max_servers is decreased by 1. This allows for adjusting the number of handling processes without having to restart the server. AUTHOR
