高手们，帮我看看这个信息有问题吗？

最近服务器很慢！但是问题我在服务器里面确实找不到！

反映的问题主要是，下载速度很慢！上传速度还可以！

那位高手帮帮忙！！我快郁闷四了！

KERN增大NMBCLUSTERS的值,这么重负载,怎么也得提到16384
KERN里设置
options         NMBCLUSTERS=16384
options         MAXDSIZ="(1024*1024*1024)"
如果还不行,NMBCLUSTERS再提到32768

我直接就改到了32768
重起以后好了一会又不行了！

主要问题是，下载速度很慢！
不管web还是ftp
都慢
服务器里还有proftpd+qmail
