[-- Attachment #1.1: Type: text/plain, Size: 463 bytes --]

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
