Hi all,
We stuck a 60 GB OCZ "Core Series" SSD in a Dell T5400 (dual quadcore,
16GB RAM, SATA II 7200 RPM disk) and did some comparisons between
running with our index on disk, vs. on SSD. I can't really talk about
what the app does, but I can share the difference in performance; see
enclosed PDF.
We have a 15GB index and a 20GB bdb, both of which are on the SSD.
Pretty amazing performance difference. "Go buy one now." :)
(The x-axis is ms/request, the y-axis is percentile. So, "65% of SSD
requests took 120ms or less", for example).
Oops -- attachments not allowed. I stuck the PDF on the wiki:
http://wiki.apache.org/lucene-java/SSD_performance
If you dig, you can find the PDF there as an attachment, perhaps at
http://wiki.apache.org/lucene-java/SSD_performance?action=AttachFile&do=view&target=combined-disk-ssd.pdf
cheers,
Eric
