description: creating buffer with 20 MB size. reading and appending readed size
into StringBuilder. after reading - show StringBuilder contents. on my machine
with Mustang b101 we read about 1440
bytes every time, instead of read 20 MB. have great perfomance problem and need
REAL buffer, but dont know what to do...
