Sanaei f52c3c4837 perf(clients): make the clients page scale to large panels
The clients page was slow on panels with many clients for two independent
reasons: the server rebuilt the whole picture on every request, and the
browser rebuilt the whole table on every poll.

Server side, ListPaged loaded every client row, every client_inbounds link
and every client_traffics row into Go memory, then filtered, sorted and
paginated in a loop -- on a request the page repeats every five seconds.
Every predicate now runs in SQL and only the requested page's ids are
hydrated, so the cost tracks the page size rather than the client count.
Measured on SQLite with a realistic status mix: the default view at 100k
clients goes from 1,072ms to 64ms. Behaviour is preserved deliberately in
the subtle places -- the cross-panel global-traffic overlay is folded into
the same used-bytes expression the predicates and sort use, LIKE wildcards
are escaped so a search for "a_b" stays literal, and the two different
tiebreak rules the in-memory comparator had are reproduced per sort key.

The summary's per-bucket email lists are capped at 200 with exact counters
beside them. They only back hover popovers, but shipping every match made
the response grow with the panel: at 100k clients it carried ~42k emails,
and the page revalidated all of them through a strict Zod parse every five
seconds. The popover now shows a "+N" chip for the remainder.

Browser side, the page fired three sequential list requests per load and
threw the first two away: the query went out before the persisted sort was
applied, and again before the configured page size was known -- 0 meaning
"one long page" is indistinguishable from "not loaded yet". The page size
is now derived rather than mirrored through an effect, and the previous
visit's value is remembered so the single request goes out at mount instead
of queueing behind /setting/defaultSettings.

Then the per-poll work. Reading isFetching made it a tracked property, so
the refetch interval notified twice per cycle and re-rendered the page even
when structural sharing left the data identical. Xray reports a traffic row
per client whether or not it moved bytes, so the speed map was mostly zeros
and was replaced wholesale every push; zero rows are now dropped and an
unchanged result returns the previous object, which lets React bail out
instead of re-rendering. The five Tooltip-wrapped buttons and the inbound
chips per row do not depend on traffic at all and are now memoised, keyed on
the email because a push replaces the row object of every client whose
counters moved. antd's hashed:false drops 3,311 :where(.css-<hash>) wrappers
and 29% of the generated stylesheet, and a pinned cssVar key stops each of
the eleven page-level ConfigProviders minting its own token scope.

Two callers that only need the mutations, GroupsPage and ClientBulkAddModal,
no longer start the list query -- the groups page had been polling the full
paged list every five seconds for data it never renders.

3x-ui

Release Build GO Version Downloads License Go Reference

3X-UI is an advanced, open-source web control panel for managing Xray-core servers. It provides a clean, multi-language interface for deploying, configuring, and monitoring a wide range of proxy and VPN protocols — from a single VPS to multi-node deployments.

Built as an enhanced fork of the original X-UI project, 3X-UI adds broader protocol support, improved stability, per-client traffic accounting, and many quality-of-life features.

Important

This project is intended for personal use only. Please do not use it for illegal purposes or in a production environment.

Features

  • Multi-protocol inbounds — VLESS, VMess, Trojan, Shadowsocks, WireGuard, Hysteria2, HTTP, SOCKS (Mixed), Dokodemo-door / Tunnel, and TUN.
  • Modern transports & security — TCP (Raw), mKCP, WebSocket, gRPC, HTTPUpgrade, and XHTTP, secured with TLS, XTLS, and REALITY.
  • Fallbacks — serve multiple protocols on a single port (e.g. VLESS and Trojan on 443) using Xray's fallback support.
  • Per-client management — traffic quotas, expiry dates, IP limits, live online status, and one-click share links, QR codes, and subscriptions.
  • Traffic statistics — per inbound, per client, and per outbound, with reset controls.
  • Multi-node support — manage and scale across multiple servers from a single panel.
  • Outbound & routing — WARP, NordVPN, custom routing rules, load balancers, and outbound proxy chaining.
  • Built-in subscription server with multiple output formats and custom page templates.
  • Telegram bot for remote monitoring and management.
  • RESTful API with in-panel Swagger documentation.
  • Flexible storage — SQLite (default) or PostgreSQL.
  • 13 UI languages with dark and light themes.
  • Fail2ban integration for enforcing per-client IP limits.

Quick Start

bash <(curl -Ls https://raw.githubusercontent.com/mhsanaei/3x-ui/master/install.sh)

To install a specific version, append its tag (e.g. v3.4.0):

bash <(curl -Ls https://raw.githubusercontent.com/mhsanaei/3x-ui/master/install.sh) v3.4.0

To install the rolling dev build (latest per-commit pre-release from main, not a stable release), pass dev-latest:

bash <(curl -Ls https://raw.githubusercontent.com/mhsanaei/3x-ui/master/install.sh) dev-latest

During installation a random username, password, and access path are generated. After installation, run x-ui to open the management menu, where you can start/stop the service, view or reset your login credentials, manage SSL certificates, and more.

For full documentation, please visit the project Wiki.

Unattended install

The installer also runs non-interactively for cloud-init. Set XUI_NONINTERACTIVE=1 (or pipe with no TTY) and it installs end-to-end with zero prompts, generating random credentials and writing them to /etc/x-ui/install-result.env. See deploy/ for:

Supported Platforms

Operating systems: Ubuntu, Debian, Armbian, Fedora, CentOS, RHEL, AlmaLinux, Rocky Linux, Oracle Linux, Amazon Linux, Virtuozzo, Arch, Manjaro, Parch, openSUSE (Tumbleweed / Leap), Alpine, and Windows.

Architectures: amd64 · 386 · arm64 (aarch64) · armv7 · armv6 · armv5 · s390x.

Database Options

3X-UI supports two backends, chosen during the install:

  • SQLite (default) — a single file at /etc/x-ui/x-ui.db. Zero setup, ideal for small and medium deployments.
  • PostgreSQL — recommended for high client counts or multi-node setups. The installer can install PostgreSQL locally for you, or accept a DSN to an existing server.

At runtime the backend is selected via environment variables (the installer writes these to /etc/default/x-ui for you):

XUI_DB_TYPE=postgres
XUI_DB_DSN=postgres://xui:password@127.0.0.1:5432/xui?sslmode=disable

Migrating an existing SQLite install to PostgreSQL

x-ui migrate-db --dsn "postgres://xui:password@127.0.0.1:5432/xui?sslmode=disable"
# then set XUI_DB_TYPE and XUI_DB_DSN in /etc/default/x-ui and restart:
systemctl restart x-ui

The source SQLite file is left untouched; remove it manually once you have verified the new backend.

Docker

The default docker compose up -d keeps using SQLite. To run with the bundled PostgreSQL service, uncomment the two XUI_DB_* env lines in docker-compose.yml and start with the profile:

docker compose --profile postgres up -d

The image bundles Fail2ban (enabled by default) to enforce per-client IP limits. Fail2ban bans offenders with iptables, which requires the NET_ADMIN capability. docker-compose.yml already grants it via cap_add; if you start the container with docker run instead, add the capabilities yourself, otherwise bans are logged but never applied:

docker run -d --cap-add=NET_ADMIN --cap-add=NET_RAW ... ghcr.io/mhsanaei/3x-ui

Environment Variables

XUI_TUNNEL_HEALTH_PROXY Proxy the probe is sent through; point it at a local xray inbound so the probe tests the tunnel (e.g. socks5://127.0.0.1:1080). Empty means the probe only checks host connectivity

XUI_TUNNEL_HEALTH_TIMEOUT Per-probe timeout 10s
