Those latencies look like the difference between a couple of disk seeks and
reading something that's already in the os cache.
The dynamic snitch will favor nodes with lower latencies. Once a node has
served enough reads, it might not have to hit disk very often, which
produces lower latencies. S
all,
what would explain a huge different (12ms vs 0.1ms) in read latency from
node to node. i've got a 4 node cluster w/ replication factor of 3
using hector. i'm seeing these numbers with nodetool cfstats.
thx,
