[Koha] Koha indexing - files

[Chad Roseburg]

We are currently setting up a server and have a question about the location
of the zebra indexes.
Is /var/lib/koha/instancename/biblios/ the only place zebra keeps the index
files it writes to during the indexing process?

We are considering mounting the index files to a separate high-performance
disk array in hopes of improving performance during the indexing process --
has anyone experimented with something like this?

Thanks!
