I don't wanna believe you. Are you sure about memory issue? Do you run lighttpd in VPS server or dedicated server? How many PHP requests per second do you need? If you need 25 PHP requests per/sec, then
25 * 0.1sec/php = 2.5 php process. Let us round it to 3 process. Here is some optimized config:
Code:
fastcgi.server    = ( ".php" =>
        ((
                "bin-path" => "/usr/bin/php-cgi",
                "socket" => "/tmp/php-cgi.socket",
                "max-procs" => 3,
                "idle-timeout" => 30,
                "bin-environment" => (
                        "PHP_FCGI_CHILDREN" => "50",
                        "PHP_FCGI_MAX_REQUESTS" => "500"
                ),
                "bin-copy-environment" => (
                        "PATH", "SHELL", "USER"
                ),
                "broken-scriptfilename" => "enable"
        ))
)
Once updated you need to install xcache
Redhat / CentOS / Fedora Linux Install XCache for PHP 5
XCache - Boost PHP Performance - Trac

You also need to optimize mysql by enabling mysql query cache
MySQL :: MySQL 5.0 Reference Manual :: 7.5.4 The MySQL Query Cache
Enable the query cache in MySQL to improve performance

Also note that sometime VPS put restrictions on open file and connections.
