Bump DEFAULT_DISTRIBUTION_BUFFER_SIZE to 128 MB

michaelklishin · michaelklishin · commit 75b2473d4fbe · 2017-07-27T18:28:02.000+03:00
After 24 hours of testing we haven't observed any anomalities or regressions. With this change multicast (mirroring) processes should be suspended less frequently, resulting in less variable throughput for mirroring (with link throughput of 1 GBit/s or greater). Closes #1306. [#149220393]
