Comment(by imincik1):
In my situation, I have whole home directory including GRASS data dir on
NFS 4 mount.
1. After short investigation, it seems, that setting PRAGMA
synchronous=OFF on SQLite db has no effect.
2. What was a great change was moving '.tmp' directory from my mapset
outside of NFS (by using symlink). v.in.ogr was 8 times faster.
So my idea is, is it possible to have some environment variable, which
could define global alternative directory for temporary files ? This could
improve situation for all modules which are using temporary files (for
example v.random is not using).
