 Description  « Hide
Building indexes when restoring database takes lot of time if TempCacheLimit is not properly selected BEFORE beginning of this operation.
The default value of TempCacheLimit (64M) mean that almost all sorting info will be swapped onto TempDirectories folder(s).
And even if TempDirectories is set to /dev/shm ("ram disk") - it is not panacea because as soon as total size of TempCacheLimit is exceeded the speed of writing immediatelly decreases.

It will be useful to implement command line switch to GBAK utility for setting TempCacheLimit to some value - only at the time of restoring.
