apache linux php

Linux 7.5GiB 内存,4 个 EC2 计算单位(2 个虚拟内核,各含 2 个 EC2 计算单位),850GB 本地实例存储,64 位平台
Apache2.2 PHP5.3 mysql连接的远程数据库服务器
Google Analytics实时检测显示基本同时500、600、700到1000多人在线
Apache perfork模式
现在设置的是
StartServers 20
MinSpareServers 20
MaxSpareServers 40
ServerLimit 10000
MaxClients 5000
MaxRequestsPerChild 3000

netstat -n | awk '/^tcp/ {++S[$NF]} END {for(a in S) print a, S[a]}' TIME_WAIT 8496
FIN_WAIT1 28
FIN_WAIT2 393
ESTABLISHED 226
SYN_RECV 23
CLOSING 1
LAST_ACK 4
ps -ef | grep httpd | wc -l
267

top显示了一堆httpd进程、、
问题:
perfork里面的StartServers、MinSpareServers、MaxSpareServers、ServerLimit、MaxClients、MaxRequestsPerChild都啥意思啊、哪控制同时响应数啊、进程数、子进程数,top显示的每一条httpd算一个进程还是子进程?、perfork设置的有啥问题没、、Apache设置还需要注意啥呢
