Всем привет.
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.
Rgds,
Rider
