On my system in the shack (800 Mhz athlon with kernel 2.4.19) the cw is 
extremely choppy from 30 wpm upwards and weight is 0.
I use it with weight =3, which is o.k. up to 51 wpm. 
This is strange, as top says the processor is 95 % idle.

On my development system (1.4 GHz athlon with kernel 2.4.21) I can use 
weight=0 or weight=1

> 2) At what speeds do you use cwdaemon?
upwards from 30 wpm (tlf indicator)

> 3) What weight value are you using?
w=3 on the slower machine
w=1 on the faster one, although w=0 would do o.k. (I like "heavy" keying; I 
have learned it with a mechanical bug :-)

sidetone trx (OMNI VI + with QSK).

> 5) If you use the sidetone, do you use the serial or parallel interface?
always parallel interface.
