\r
85 I use ext4 with data=3Dordered, and while notmuch is writing the
\r
86 Xapian database, most I/O stalls on the machine:
\r
88 - Firefox does not get any mouse events
\r
89 - Vim blocks writing the viminfo file
\r
90 - All disk operations queue for multiple seconds.
\r
92 So no, ext4 is not a solution. Is it just me, or should no
\r
93 filesystem of this world be able to hog a system this badly? I think
\r
94 the culprit is the IO-scheduler.
