发现内存大量闲置，又闲的蛋疼，于是决定分出2G内存给浏览器做Cache。
1. 步骤
1.1. 将以下分隔符内代码保存为ramdisk.sh & chmod +x ramedisk.sh
---ramdisk.sh-----
#!/bin/sh
mount_point=/Volumes/ramdisk
ramfs_size_mb=2048
RamDisk (){
ramfs_size_sectors=$((${ramfs_size_mb}*1024*1024/512))
ramdisk_dev=`hdid -nomount ram://${ramfs_size_sectors}`
newfs_hfs -v 'RAM Disk' ${ramdisk_dev}
mkdir -p ${mount_point}
mount -o noatime -t hfs ${ramdisk_dev} ${mount_point}
mkdir ${mount_point}/chrome
mkdir ${mount_point}/firefox
mkdir ${mount_point}/safari
rm ~/Library/Caches/Google/Chrome/Default/Cache
rm ~/Library/Caches/com.apple.Safari
ln -s ${mount_point}/chrome ~/Library/Caches/Google/Chrome/Default/Cache
ln -s ${mount_point}/safari ~/Library/Caches/com.apple.Safari
}
RamDisk
----eof-----------
1.2. 将ramedisk.sh 加入当前用户的启动项 [System Preferences->System->Accounts->Login Items]
1.3. Firefox需要另外设置 about:config中添加browser.cache.disk.parent_directory项，类型为string，值为 /private/ramdisk/firefox/
2. 磁盘速度测试（单位为M/S）:
2.1. HD
2011-04-08 22:34:29.420 AJA System Test[10449:1707] Average read rate = 51.95
2011-04-08 22:34:29.421 AJA System Test[10449:1707] Average write rate = 54.03
2.2. RAMDISK
2011-04-08 22:34:53.170 AJA System Test[10449:1707] Average read rate = 1642.24
2011-04-08 22:34:53.171 AJA System Test[10449:1707] Average write rate = 1835.27

sparanoid MOD 曾经用过的小工具： http://boredzo.org/make-ram-disk/
把 ramdisk 分给浏览器当缓存没必要吧，我一般是把 ramdisk 作为 Photoshop 的 Scratch 盘 如果有 64GB Mac Pro 的话，分 16GB 全部给 Photoshop 后性能提升会更爽 |
