Hello - [NT4 Server SP6a, Exchange enterprise 5.5 SP4]
Has anyone used and compared Exchange anti-virus products that employ different scanning methods, e.g. MAPI/VSAPI/ESE? I'm curious about the performance differences between the implementations. We're currently using a VSAPI-based product and the performance is pretty dreadful - loads of archiving/synchronization errors and people with incomplete offline mailbox replicas. The anti-virus software is patched and up-to-date and we've adjusted the "OpenRetryDelay" several times, to no avail. The server hosts about 120 active mailboxes - some pretty big - but the store databases have a dedicated 6-drive, ultra 160 SCSI, raid 5 volume. The transaction logs are on a different volume. PRIV.EDB is currently about 45GB in size and the problem affects every user on the server. I just wondered if there were any outright conclusions that favoured one approach or product over the others. Also, I'd be interested if anyone can confirm that the VSAPI interface builds a single, potentially long queue of attachments to be scanned, introducing a bottleneck ?
