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).
