Alexander Motin 891852cc12 Change 'load' balancing mode algorithm: ... - Instead of measuring last request execution time for each drive and choosing one with smallest time, use averaged number of requests, running on each drive. This information is more accurate and timely. It allows to distribute load between drives in more even and predictable way. - For each drive track offset of the last submitted request. If new request offset matches previous one or close for some drive, prefer that drive. It allows to significantly speedup simultaneous sequential reads.
