> Potentially file output stream could be opened using NIO with `java.nio.file.StandardOpenOption.SYNC` option. It probably (need to test) will do the trick but I am wondering if there will be any noticeable performance penalty since it'll happen on every write I disagree, if the performance penalty was be negligible, that option would be on by default. Microsoft will probably solve the problem sooner or later, so I see no reason to modify the behavior for all Log4j Core users, however we can: - implement #2117 or at least part of it. The usage of NIO has the advantage of using the same `StandardOpenOption`s on UNIX and Windows. - add a configuration option to **all** [file appenders](https://logging.apache.org/log4j/2.x/manual/appenders/file.html) and [rolling file appenders](https://logging.apache.org/log4j/2.x/manual/appenders/rolling-file.html) that accepts a comma-separated list of `StandardOpenOption`s. > Does [immediateFlush](https://logging.apache.org/log4j/2.x/manual/appenders.html#immediateFlush) not help? That would be really strange: `immediateFlush` should only flush the **Java** buffers (mostly our buffers, but some implementations of `OutputStream` also have buffers), while the problem here seems to be related to OS buffers that are not _synced_ with the underlying device. -- This is an automated message from the Apache Git Service.
