Now CPU is not overloaded. On the contrary it overloading is about 1-3%.
Profiling gives such results:

Routine Name       Time    Time with Children    Shared Time    Hit Count
ISC_event_wait    171,70    172,64                99,46    8642
enterFastMutex    124,45    124,80                99,72    34410
wait_for_request   40,61    129,46                31,37    2939
PIO_write          10,10    10,10                 99,96    2550

Classic acts very slow as compared with Super when inserting data.

My platform configuration is:
OS: Windows XP SP 2, x86 - 32 bit;
CPU: Athlon 64 X2 Dual.
RAM: 2Gb
