We used OO design to support various deserialization methods to mimic Python lists, sets, and dictionaries, using LMDBs byte-based key-value records. The results were immediately noticeablethe memory usage on the hosts decreased by 4.5%, and we were able to add more processes running instances of our application code.

Challenges Large packet size One of the main challenges is the size of the Kyber768 public key share, which is 1184 bytes. This is close to the typical TCP/IPv6 maximum segment size (MSS) of 1440 bytes, but is still fine for a full TLS handshake. However, the key size becomes an issue during TLS resumption.
