Hello Rick,
Thanks for the response.

Oops. Sorry. I was under the impression that clearing the Subject field would suffice.

Yes, we know about bufferbloat. The latencies are not natural; they're caused by upstream ISP modems.

I wouldn't be surprised if Linux autotuning didn't play all that well here either, which would be another reason to go with explicitly set socket buffer sizes.

Is this the -- -s command line option?
