Package: sysstat Version: 9.0.6-1 Severity: wishlist Hello,
the periodic activity data collector sadc (sa1) uses fdatasync() to synchronize its written data down to disk. This puts a real pain on flash devices and is most likely not really needed. Neither mrtg nor atsar fsync() their data and work well anyways - I'm not using collectd, but a quick crawl over its code didn't show up any f*sync() as well. Such "manual" syncs undermine any tuning of the vm's write behaviour. Thus, it would be nice if this fdatasync() could be avoided - at least via commandline option. This is most likely something to forward upstream. Thanks for your work & regards Mario -- A: Because it messes up the order in which people normally read text. Q: Why is top-posting such a bad thing?
