请问freebsd 打什么指令查看总实体记忆体大小

fscar

伺服器启动时 在bois里 查看是4gb

我打top查算 怎才3gb多
Mem: 363M Active, 519M Inact, 139M Wired, 100K Cache, 112M Buf, 1983M Free

谢谢指导

你是x86版吧

请问我现在要下找哪个64位元的FREEBSD
以前我是下找这个 32位元 ISO-IMAGES-i386
http://ftp.isu.edu.tw/pub/FreeBSD/

当然是官网下载了，呵呵。我就在官网下的64位

跟64位没什么关系吧？4G以上内存才使用64位的比较好些，你这才4G

楼主为何不去官网看看呢？我四级22分的人都能看懂。

tecer 发表于 2009-12-5 23:15

我觉得用不用64位不要受限于内存大小，不是说内存大才用64位，我原先2G内存的时候也用的64位，后来不够用，又加了2G，当然4G的时候就要用64位，要不用不全4G。
