小弟的代理服务器 近来很大一段时间速度都比较慢 打开一些常用的网页 经常存在问题
    小弟的服务器是sun v240 2G内存，公司大概有400人在上网，由于有websense拦截，此前通过代理服务器访问的服务都比较快
/var/adm/messages上报错如下：
Feb  6 13:53:19 proxy pam_auth[19720]: [ID 293258 user.error] libsldap: Status: 49  Mesg: openConnection: simple bind failed - Invalid credentials
Feb  6 13:59:24 proxy last message repeated 13 times

。。/squid/log/cache.log报错如下：

另外 此前系统一直报错说
Feb  5 15:29:47 proxy squid[10006]: [ID 702911 user.alert] Too many queued redir
ector requests (64 on 30)
我在配置文件里面把 redirector children 数量由原来的30个改为60个了 但效果不明显

请各位达人帮我看看 谢谢
