Hi, of course we are using SSDs, but 4kB is still a tiny amount, when you have to wait for the SSD read roundtrip every time. The CPU is idle at about 10%.. The Linux kernel does not seem to perform a readahead, probably because of the random access structure.
For some reason the QueryParallelism feature does not work either. No change in the speed. Regards Sebastian -- Sent from: http://apache-ignite-users.70518.x6.nabble.com/
