Ok now PreviousSegmentLost shows. Seems like Os X is missing 0,3% of
packets. I tried to capture data into 200MB pieces of files, average
speed rate was 63Mbps. OS needs some fine tuning I think.
What Linux flavor are you using and what hardware, if I may ask?
Bottleneck could be writing to HDD is so large pieces..?
I have PowerPC G4 with 1,5GHz processor
Bus speed is 167MHz
L2 cache is 512kB
HDD is Hitachi ATA disk 74,53GB
# jarno

I would be interested in hearing how high sustained throughput you can
capture with
Mac OSX.
For linux built capture devices with a good pci bus, good NICs and a
good and striped disk subsystem you should be able to capture near
full line rate.
With windows as the platform you can, in my experience, never capture
very high bitrates before it starts dropping packets.
