: : http://proxy.nsysu.edu.tw/ <-建議先把裡面一些古早文件看完
: 恩 看過了
: 所以我用的是 24 個 cache_dir * 32 * 64
: 壓在 65535 以下
: : diskd
目前跑起來
遇到一個問題
處理的效能 真的比 之前用 linux 慢
squid 的設定都一樣...

我總共調整了 以下的參數

OS: FreeBSD (proxynew)

1.磁碟分割 切成 4個 Partition
每個 Partition 在分為 2個 LABLE
共 8 個 cache_dir
newfs 參數下 -b 8192 -f 1024 -i 4096

2.squid cache_dir 用 diskd 跑
/boot/loader.conf
kern.ipc.msgmnb=16384 # Origin: 2048
kern.ipc.msgmni=96 # Origin: 40
kern.ipc.msgseg=2048 # Origin: 2048
kern.ipc.msgssz=64 # Origin: 8
kern.ipc.msgtql=5120 # Origin: 40
kern.geom.debugflags=16
machdep.hyperthreading_allowed=1

3.kernel 加
options SMP # Symmetric MultiProcessor Kernel
options MAXFILES=16384


OS:Dabian (proxyold)

1.磁碟分割為 8個 Partition
4個 MA 4個 SL
格式用 ext3

2.啟動squid 時 先下
ulimit -HSd unlimited
ulimit -HSn 32768
ulimit -HSu unlimited

3.cache_dir 使用 aufs


測試的結果 如下...

明顯的 NEW 那台比較慢...
還有什麼可以調嗎?
