perf: remove indirection overhead caused by iface usage

[dkharms]

Description

Return of the prodigal son (we've lost this change after tough battle with pull request conflicts resolving).

---

I got following results:

• In a mixed scenario I observe decrease in CPU usage (on average) from 4.44 CPU to 4.30 CPU (4%) (grafana);
• In a bulk scenario I observe decrease in CPU usage (on average) from 4.48 CPU to 4.33 CPU (4%) (grafana);

Although this change does not have a visible impact on bulk latency (in fact, the bulk latency in the comparison branch is lower by about 1 ms on average), that’s fine — LIDs are sorted in the background.

• I have read and followed all requirements in CONTRIBUTING.md;
• I used LLM/AI assistance to make this pull request;
