Am I correct in assuming that you got to the 20MB/sec number by taking our 3 bytes per point number times the number of data points? The input is actually much higher than that. Data points over the network look like this: cpu_idle,host=serverA,region=uswest value=23.0 1454617920 That's actually a toy example. Most real data would probably have more tags and longer measurement names. Obviously that's much more than 3 bytes. We persist that to disk in a write ahead log (WAL) and then later we can do compression and compactions on the data to squeeze it down to 3 bytes per point. However, that takes more than a single write against the disk to get to. Run a load test against it. See how much network bandwidth you can use. See what your HD utilization looks like. My guess is you'll be surprised by what you see.
