Rate Limiting Mechanism for LWS

Currently, LWS (LSF Web Services) does not provide a built-in rate limiting mechanism similar to lsfproxyd. In high-load scenarios, where a large number of concurrent requests are sent to LWS, this can lead to performance degradation or service instability. Kindly introduce a rate limiting feature in LWS with functionality similar to lsfproxyd.

    After a call with Shyam we better understand the challenge - that it's user's writing their own AI agents, which are in turn calling LSF and generating additional load.
    We will consider this in future work

    As LSF uses a proprietary protocol it is challenging to provide any form of traffic shaping. This is why lsfproxyd was introduced for very large clusters.

    However, LWS is a rest api over http/https. As such, industry standard mechanisms to be used - such as load balancing and traffic shaping. For example:


    Nginx: limit_req and limit_conn modules

    • Allows per‑IP request rate limiting

    • Supports burst handling and queueing

    • Can return native HTTP 429 responses

    Apache HTTPD: mod_ratelimit, mod_evasive, mod_security

    • Controls request throughput

    • Detects abusive patterns and throttles or blocks clients

    HAProxy: stick‑tables for rate limiting

    • Very efficient at connection‑level and request‑level throttling

    • Can enforce global or per‑client quotas

    As such, we have no plans to add a proprietary mechanism.
