[PD] latency

How do you measure the latency on your machines ? 

I tried to use the "latency.pd" patch in the "tools" folder, but the latency I 
get is usually about 340 ms, which looks wrong : when I route an incoming 
signal from [adc~] to [dac~] (a kind of audio bypass patch), I don't hear any 
latency between the direct source and the output. Therefore the latency of my 
computer should be at least lesser than 10 ms ; my sound card is set to 128 
samples (3 ms)
