Ah yes, the beautiful new links in Windows 6. These are 'symlinks' in
name only - they operate *very* differently from LUNIX symlinks, and
sadly, not quite so well. NTFS is one of the best things about
Windows, but it's architecture is not well suited to 'on-the-fly'
redirection, as there are many
Indeed I would never actually use it, but symlinks do exist on Windows.

The Solr index directory lives directly on the SSD (running on Windows
- where the word symlink does not appear in any dictionary within a
100 mile radius of Redmond :-)
Currently, the main limiting factors of SSD are cost and size. SSDs
will get larger over time. Splitting indexes across multiple
Interesting. Do you make a symlink to the indexes or is the whole Solr
directory on SSD?

Just to add a few cents worth regarding SSD...
We use Vertex SSD drives for storing indexes, and wow, they really
scream compared to SATA/SAS/SAN. As we do some heavy commits, it's the
commit times where we see the biggest performance boost.
In tests, we found that locally attached 15k SAS drives
Thanks folks!

That link appears to be foo'd, and I can't find the original doc.
But others (mostly on the user's list historically) have seen very significant
performance improvements with SSDs, *IF* the entire index doesn't fit
in memory.
If your index does fit entirely in memory, there will probably be some
I haven't tried it with Solr yet, but with straight Lucene about two years
ago we saw about a 40% boost in performance on our tests with no changes
except the disk.
