Description
This is the default configuration we use for UNICAST3 and NAKACK2:
<pbcast.NAKACK2
xmit_interval="1000"
xmit_table_num_rows="100"
xmit_table_msgs_per_row="10000"
xmit_table_max_compaction_time="10000"
max_msg_batch_size="100"
resend_last_seqno="true"/>
<UNICAST3
xmit_interval="500"
xmit_table_num_rows="20"
xmit_table_msgs_per_row="10000"
xmit_table_max_compaction_time="10000"
max_msg_batch_size="100"
conn_expiry_timeout="0"/>
Bela recommended making a smaller `xmit_table_msgs_per_row`:
Wow. I suggest 50 * 1024 or 20 * 2048 is good enough, as the table will expand/shrink on demand anyway.
Note that you can also set xmit_table_max_compaction_time, but I would use the default (30s / 60s).

The [number of rows] is not the problem, as JGroups will dynamically create more, or remove unused ones when compacting, but the size of the rows is static.
