I have a mailhub with qmail-scanner-1.16 that scan the incomings mails for 7 domains (6500-7000 mails/day), the load is light and runs on a dedicated Pentium II 350 Mhz 256 Mb Ram, HD IDE.

Recently I installed qmail-scanner-1.2rc3 on another computer and move to this computer the mail for a domain with a very low traffic (20-30 mails/hour). This box is Pentium III 1000 Mhz 512 Mb Ram, HD SCSI. No other sw is running on this box but the elapsed times are very much higher.

Below are some examples from the logs

I didn't debug init_scan in this box

This isn't really a problem, at least for me, but I wonder what is going on, the second box is more powefull but process the messages slower. And in the second box you can see that the antivirus job (init_scan) takes less than 50% of the time of processing a message.

Any ideas?
