Hi,
we just updated riak cluster to 1.4.2 from 1.3.0 and as suggested in the
rolling upgrade docs I did a "riak-admin diag" and got the following
messages:
[root@37VQMW1 riak]# riak-admin diag
[critical] net.core.wmem_default is 229376, should be at least 8388608
[critical] net.core.rmem_default is 229376, should be at least 8388608
[critical] net.core.wmem_max is 131071, should be at least 8388608
[critical] net.core.rmem_max is 131071, should be at least 8388608
[critical] net.core.netdev_max_backlog is 1000, should be at least 10000
but according to the doc:
http://docs.basho.com/riak/latest/ops/tuning/linux/
these configs are optional and only help performance on a 10GB network
(we only have 1GB). So should I change the values or leave them alone?
Ingo
