  OK. I did few more tests and got following results for transmited bytes.
Interface is shaped at 512kbps, tests run for 100 seconds.

  - tc class reports 5910888 bytes (~432kbps)
  - ifconfig eth1 reports 6704130 bytes (~523kbps)
  - tc rate reports rate 66140bps (6614000 bytes, 516kbps)

  As you see difference is quite essential.

  But if I count packets:

  - tc class reports 15444 packets
  - ifconfig eth1 reports 15504 packets

  Results are practically the same.

  Could it be that HTB somewhere does not update bytes statistics?
