Hello!
Running Cassandra 2.2.9 with a 4 node cluster with replication factor 4.
When running anti-entropy repair is it required to run repair on all 4
nodes or is it sufficient to run it on only one node?
Since all data is replicated on all nodes i.m.o. only one node would need
to be repaired to re

er 26k/s+ inserts with CL_QUORUM. With
compaction throttling enabled at any rate it just couldn't keep up. With
throttling off, it runs smoothly and does not appear to have an impact on
our applications, so we always leave it off, even in EC2. An 8GiB heap is
too small for this config on 1.1. YM
ems at 5 or lower.
20 is too high for large memory servers IMO.

I would check /etc/sysctl.conf and get the values of
/proc/sys/vm/swappiness and /proc/sys/vm/vfs_cache_pressure.
If you don't have JNA enabled (which Cassandra uses to fadvise) and
swappiness is at its default of 60, the Linux kernel will happily swap out
your heap for cache space. Set swappines
