Made a "direct translation" wordpress 2.6.5. This gave a slight increase in arbitrariness. The engine began to eat about 1.7 MB less memory (depending on hosting) and the page generation time was slightly reduced. On home localhost the numbers are as follows:
Russian wordpress 2.6.5 : 9.8MB | 0.362
Russian wordpress 2.6.5 of my build : 8.2MB | 0.286
