SpeedServer is a Sider Lua module for PES 21 created by nesa24 (PlayPES.rs). It provides granular control over the game speed during matches, allowing fractional values instead of only the integer steps (-2, -1, 0, +1, +2) exposed by the base game’s options menu.
The file is named SpeedServer2.lua in the FL26 installation, likely a renamed or updated version bundled by the SmokePatch team. There is no publicly documented “SpeedServer1” vs “SpeedServer2” distinction — nesa24’s original releases are simply called “SpeedServer”.
How it works
SpeedServer hooks into Sider to write a floating-point value into the same memory address that the game uses for its internal speed setting. This allows decimal values (e.g., -0.5, -1.95, 0.3) rather than only whole integers, giving much finer control over match tempo.
The value is not a multiplier or percentage — it maps directly to the game’s internal speed parameter, just with finer granularity. 0 is default speed, negative values slow down, positive values speed up.
Configuration
The module is configured via SpeedServer2.ini in the SiderAddons/modules folder:
game_speed = -1.95The original SpeedServer also supports per-team speed values via a config file, where different home stadiums can have different speeds — reflecting how real-life football tempo varies between venues and teams.
Game speed can also be changed during a match via the Sider overlay without editing the config file.
Common community values: -0.5 to -1.5 for realism, 0 to +1 for an arcade feel.

Current configuration
This module is active in my FL26 setup, set to -1.95 (slow simulation pace).
