["Ivan Kelly (JIRA)" <ji...@apache.org>]

Ivan Kelly commented on BOOKKEEPER-716:
---------------------------------------

[~hustlmsp], could you expand on the rationale for this change? In the description you mention corruption, but this seems more like a perf thing. Do you have any perf numbers for this change? (also, I would be very interested if you could share perf numbers from 715 & 717).

> it would be better to pad journal writes to align sector size, which to avoid second syncing corrupt an already synced sector/page.
