[lisp-snmp] Memory usage of ASN.1 library

[John F. <jf...@ms...>]

Dear Chun Tian,

We are struggling with the memory usage of our application.

It seems that our garbage collector is rather tiresome (we are using
Allegro CL 8.1) and struggles when large amounts of garbage are
generated.

In the ASN.1 parsing, according to a sensible profile (from SBCL, the
Allegro space profiler doesn't give useful information), one of the
biggest generators of garbage in our application is

784,921,696 |    72,584 |   0.000000 | ASN.1:OID-NUMBER-LIST

(about 50% of the consing).

You mention in the source code that this method could easily be improved
with a hash-table.

How about storing a number-list slot in each object-id instance?

Any advice or ideas would be helpful.
