I sent this to Bruce but forgot to cc pgsql-hackers, The patches are likely to go into 2.6.6. People interested in extremely safe fsync writes should also follow the IDE barrier thread and the true fsync() in Linux on IDE thread

Accessing the web archive is slow from Hong Kong but I just wanted to point you to this lkml post which shows why O_SYNC is much faster than fsync (at least on ext3) http://marc.theaimsgroup.com/?l=linux-kernel&m=107959907410443&w=2 There are some pending fsync speedups on XFS also. You might want to consider pointing Tom to do this so he can get the Redhat/Fedora guys to look at the patches Hope this helps, Regards, Yusuf ----- End forwarded message ----- -- If you're not using Firefox, you're not surfing the web you're suffering it http://www.mozilla.org/products/firefox/why/ ---------------------------(end of broadcast)--------------------------- TIP 2: you can get off all lists at once with the unregister command (send "unregister YourEmailAddressHere" to [EMAIL PROTECTED])
