Hi,as I mentioned a few days ago, we're considering metapartions on SSD drives in order to optimize IMAP search performance. We have yet to run a full analysis on how much storage that would require, but a first guesstimate points towards about 20% of the net mail data for all the cyrus.* files when using SQUAT.
Bron mentioned support for xapian in 2.5, so I took a look at the branch and noticed that there isn't only support for xapian, but actually a choice of SQUAT, xapian and Sphinx. Eventually I'd like to learn the pros and cons of the various choices, but right now I have mainly one concern:
Will index files be larger with xapian or Sphinx? Will they also be stored on the metapartions? My concern is that we might run out of space on those metapartitions if we choose a different indexer ... what's the operational experience regarding that at Fastmail?
Thanks
Sebastian
