Я прогнал lmbench (http://www.bitmover.com/lmbench/) на ядрах, собранных компилятором gcc2.96-2.96-alt3 и компилятором gcc3.2-3.2.1-alt2 ядро alt1 - компилятор 3.2, alt2 - 2.96 Прошу посмотреть и проанализировать. Единственное НО - я, к сожалению, на 3.2 прогнал всего один тест. Но в целом картина по моему достаточно ясна. Если у вас есть машина с процессором Intel PIII 1 гигагерц - я могу выслать базу и сравним результаты.
