qmail-scanner-queue.pl runs spamassassin, razor2, pyzor, clamav, and its own internal scanner, as well as doing rbl lookups, in under 1 second per message, usually about .8 seconds for me.
The 10 second delay as someone pointed out is the default timeout for rbl lookups.
I had this problem and I recently groomed my rblsmtpd list. I was using servers that were down.
The following list may use some services that are a little agressive, though I now have no (known) issues with valid mails being bounced, but in combination with spamassassin, as well as an address known to many spammers (used to get 80+ per day), a few spams make it into my inbox per week.
More info about these hosts can be found through their websites.
Also, by following /var/log/qmail/smtpd/current, you can follow rblsmtpd's actions, for debugging, etc.
FYI: (live, fast responding rbl hosts as of 1/26/03)

Hi people !
I want to install Spamassassin and Clam Antivirus with vpopmail ! Do you suggest any high speed scanning tool ?
I know qmail-scanner.pl, but is this a fast method ? Meanwhile.. My Spamassassin needs aproximately 10 seconds for scanning one message. Is this the normal duration ?
My "homegrown" Mailserver uses vpopmail/qmail and has about 200 Mails per day :)
Thanks very much, knom.
