The results from more testing. We tried the following settings for the
items rmem_default, rmem_max, etc.
- 96k (98304)
- 128k (131072)
- 192k (196608)
Values were the same on both systems under test. No significant changes in
results. We saw the same kind of results [worst drop off at about 7200 byte
messages, drop to about 10% expected throughput]. Should I try larger sizes
[say 1meg] before giving up on this?
Is there something else I can try such as settings for the congestion
avoidance?
Thanks.
