AIF batch job takes long time to read files in directory

Hi,

I'm using Dynamics AX 2009, and I have configured AIF endpoints for inbound and outbound files. The Recurrence I put for the batch job is 1 minute, with no end date.

It works perfectly, but most of the time it is taking around 2 minutes to pick up the file from the inbound directory, and when I click to "send electronically" an invoice, it is taking around 4 to 5 minutes until the XML file gets generated in the outbound folder.

Is there any configuration that I can do to reduce this time, for example, recurrence less than 1 minute, or anything like event that makes MS Dynamics read the file in that folder, or anything else?

Thanks and regards,

Sergio
