執行時間通過在mysql上添加索引表

我正在更改具有多於200萬行的表上的索引。執行時間現在長於3000秒。我認爲任何東西在我的電腦上都有問題，因爲之前的其他更改從未在同一張桌子上花過這麼長時間。我已將所有索引與現有數據相加。有沒有人有經驗需要多少時間來改變具有200萬行存在行的索引？執行時間通過在mysql上添加索引表

我如何檢查是否有任何工作正常我的本地mysql安裝？

下面是表的定義：

CREATE TABLE `sal_forwarding` (
    `sid` BIGINT(20) UNSIGNED NOT NULL AUTO_INCREMENT, 
    `f_shop` INT(11) NOT NULL, 
    `f_offer` INT(11) DEFAULT NULL, 
    `link` VARCHAR(255) CHARACTER SET utf8 COLLATE utf8_unicode_ci DEFAULT NULL, 
    `offerCode` VARCHAR(255) DEFAULT NULL, 
    `sub2` VARCHAR(200) CHARACTER SET latin1 COLLATE latin1_german1_ci DEFAULT NULL, 
    `forwardTime` DATETIME NOT NULL, 
    `cid` CHAR(32) DEFAULT NULL, 
    `f_partner` VARCHAR(20) NOT NULL, 
    `t` VARCHAR(30) CHARACTER SET latin1 COLLATE latin1_german1_ci DEFAULT '0', 
    `toolbarUser` TINYINT(1) NOT NULL DEFAULT '0', 
    `blog` TINYINT(1) DEFAULT '0',

    `sub7` VARCHAR(200) CHARACTER SET latin1 COLLATE latin1_german1_ci DEFAULT NULL, 
    `f_affiliateId` TINYINT(3) UNSIGNED NOT NULL, 
    `browser` VARCHAR(50) DEFAULT NULL, 
    `bversion` VARCHAR(5) DEFAULT NULL, 
    `os` VARCHAR(50) DEFAULT NULL, 
    `forwardDate` DATE NOT NULL, 
    PRIMARY KEY (`sid`),

非常感謝你。
