This is still very far from usable. Various bridges and bots are still talking to `matrix-nginx-proxy` instead of the new `matrix-homeserver-proxy` role. These services need to be reworked. While reworking them, various cleanups are being done as well as adding Traefik-labels to those that need them.

# matrix-homeserver-proxy is a role which brings up a containerized nginx webserver which helps with reverse-proxying to the Matrix homeserver (Synapse, etc.).
|
|
#
|
|
# Certain services (like matrix-media-repo, matrix-corporal, identity servers, etc.) may need to capture some requests destined for the homeserver
|
|
# and handle them instead of it.
|
|
#
|
|
# This role helps other services (bots, bridges, etc.) reach the homeserver in a way that:
|
|
# - is not very direct, so as to allow for some routes (media repo, etc.) to actually go elsewhere
|
|
# - is not via the public network and/or via HTTPS, which introduces major performance penalties
|
|
#
|
|
# Performance-wise, benchmarks show that:
|
|
# - each local (container) nginx hop adds about a 200 rps penalty
|
|
# - SSL termination (on the Traefik side) adds a 350 rps penalty
|
|
# - going over the public network adds another 70 rps penalty
|
|
#
|
|
# It's something like this for an existing flow (which will be gone soon):
|
|
# 1. public network, Traefik + SSL: 70 rps
|
|
# 2. `matrix-nginx-proxy:8008`: 600 rps
|
|
# 3. `matrix-nginx-proxy:12080` 850 rps
|
|
# 4. `matrix-synapse-reverse-proxy-companion:8008`: 1000 rps
|
|
# 5. `matrix-synapse:8008`: 1200 rps
|
|
#
|
|
# Traefik was additionally benchmarked to see where the slowness comes from. Results are like this:
|
|
# 1. public network, Traefik + SSL: 70 rps
|
|
# 2. local (container) network, Traefik + SSL: 150 rps
|
|
# 3. local (container) network, Traefik without SSL: 500 rps
|
|
# 4. `matrix-nginx-proxy:8008`: 600 rps
|
|
#
|
|
# It's obvious that minimizing the number of hops helps a lot and that not using SSL and/or the public network is important.
