We still have this problem (we're on riak 1.4.9) and it's very frustrating!
Our average object size right now is ~250k. We're running with:
+zdbbl 2097151
I've tried the settings above on a 5 node test cluster, no improvement.
I then bumped both buffers up to 1048576 on all nodes - no improvem
In my testing with large but smaller binaries (median 40k), I found
that the settings gave a noticeable bump (8000 -> 1 ops/s) , but
only so far as the disk could keep up (and the disk cache, of course).
Typically, for larger objects, you're going to be disk limited most of
the time. Remember
True, but if I test random-writes of 1M objects using fio on the filesystem
-- no Riak involved -- the disk random write aggregate speed (32 fio
threads all randomly writing to one node's array) is 9.4 Gbits/sec ***per
node***, and I have 6 nodes. If Riak was distributing all writes evenly and
