But it can cause NFS client corruption and you no longer gets
synchronous write semantics (see if your app depend on that):

I highly recommend *against* setting zil_disable.
Disabling zil did improve the postgresql-import from 1 h. 45 min. to
1. h. 35 min. I get a 10 min. speedup but as the link point out
disabling has it's disadvantages. So I'll revert to the old setting.
