dovecot - Jul 2014 - fts solr database size

Hi,

Could anyone share any numbers about real life solr database
size/cpu/memory usage for
certain amounts of messages ?

We have now over 5TB of maildirs (about 5 000-6 000 concurrent imap clients)
and I'm trying to guess how much hardware might be needed.

We are no way as big as you but in terms users but our user vs mailbox size is
large.

Dovecot:
50 users
425Gb (mdbox + zlib)

Note solr only indexes folders within a mailbox when a search is done on them so
size can vary and most people dont
realise that the default type of search in Thunderbird is on
Sender/Recipients/Subject which happens localy and not on
the server so you dont get solr indexing unless the user does a custom search
and forces remote. Webmail systems though
will  tend to do server searches.
Solr:
Num Docs: 17m
Size: 4.5GB
