It is. The whole indexes pain with Cyrus is to get that speed...

Don't. It will hurt you like all hell. Instead, clean up the mess
(cyrus-makedirs will help you there), and upload all the mail to the imap
folder using a mail client.
This is trivial to do with mutt, for example. Open the maildir folder, tag
all messages with "T.<CR>", upload them all with ";s{myid@imapserver}<CR>".
Cyrus is really, really picky about what it stores in its bowels, and thus
you are well advised not to do anything to the spool that isn't done through
either IMAP, LMTP, or any of the cyrus utilities (cyrreconstruct, cyrquota,
cyrdeliver...).
BTW, Cyrus can be even faster by creating SQUAT indexes of mailboxes to
speed up the "search" operations...

When you copied the files directly, without knowing how sane they were, you
probably got Cyrus confused. There must be no "From " line, just a RFC822
message with proper EOLs (I don't quite remember what cyrus uses for an EOL
right now, probaby 0x0A) and no trailing garbage or embedded NULLs, EVER.
As long as the mailbox is still in the mailbox databases (see ctl_mboxlist),
a cyrreconstruct should rebuild the indexes. But it REALLY won't like any
message files that are even slightly out of wack.
