1) Index based mempool lcore cache
a) Limitations - Supports 4GB of contiguous memory for buffers
b) 4GB of buffer space is enough in some use cases such as smart NICs and embedded appliances
c) L3fwd application does not show performance improvements. Another way to view this is, same throughput can be achieved with less amount of resources
d) Mempool performance unit test shows an improvement of ~13% for bulk size of 32 on Arm platforms. On x86 there is a performance degradation, probably due to the patch not being optimized for x86
e) Suggestion is to show performance improvement possibly with other apps such as IPSec gateway which would place more pressure on cache.

2) GB meeting updates
a) The outstanding security issues presented to GB are not critical. Plan to address 2 CVEs in the coming release.
b) Jerin (or whoever is the TB rep) will sync up with the community on outstanding CVEs before the next GB meeting
c) DTS GPL license files - look for re-writing the files, files with alternative license, keeping the files outside of the repo (use wget)
d) GB needs more input from TB on ecosystem health

3) Python bindings
a) Link to the presentation: https://docs.google.com/presentation/d/1PgOFo4SqjWehH_YvVkGwij1XdPGIMxEPDINUI772Yb8/edit#slide=id.p
b) Owen to create a small RFC to provide a feel for changes required
c) One of the concerns is the maintenance overhead these bindings will introduce

Thanks,
Honnappa
