本人Windows 2003 企業(yè)版下，
CPU 雙 Xeon 2.8G
3G內(nèi)存 硬盤(pán)Scsi 73G 160M連接
目前Mysqld-nt,占用140m內(nèi)存，500m左右的虛擬內(nèi)存
目前服務(wù)器運(yùn)行多數(shù)都是Discuz的論壇
目前最大的一個(gè)論壇數(shù)據(jù)1g左右，
還有一些小站,還有幾個(gè)cms的小站.
現(xiàn)在是：
此 MySQL 服務(wù)器已經(jīng)運(yùn)行了 1 天 6 小時(shí)，38 分 47 秒，啟動(dòng)時(shí)間為 2008 年 12 月 26 日 12:27。
以下是MySQL的參數(shù)和運(yùn)行狀況(show statru；)
希望高手能給點(diǎn)優(yōu)化建議，非常感謝�。。�
