Subject: Forward Link v.s. Scan them all ?

Hi, all;

I have a long series of bi record to process, which have an access to
a hardware register, say, every 5 seconds.

The number of records reaches a few to several thousands. In this case,
which one of the following two options is better or no essential
difference from performance point of view?

1)Chains all the records by using FLNK and process the first one every
5 second

2)Put them all into the “5 second” scan list

I recognize that measuring it is no big deal, but I’d like to ask the
experts first expecting one of you to point out something else to
consider, which I may be overlooking, other than performance issue.

Thanks a lot in advance.
