    1.14.4+ note: As of 1.14.4, the problem this plugin was built to address has mostly been fixed in the vanilla game. The plugin will still work, and will still reduce the entityTick of Villagers, but it will not help nearly as much as in 1.14.2 or 1.14.3.
    Villager Optimiser
    Villagers have new mechanics in 1.14 that cause them to run very CPU expensive pathfinding operations. This plugin aims to reduce their impact on a server's performance by forcing them to run these pathfinding operations less frequently, all while not stopping them from functioning as normal.

    How it works
    Villagers in 1.14 now have memories; they will remember their home (bed), job site and meeting place. If a villager is missing one of these memories then they will actively search for it. This plugin more or less works by filling in these memories with some placeholder value so the villagers stop searching, and then releasing this memory every now and then so it can still perform *some* searches.

    The effect is that villagers run these pathfinding operations far less often. This doesn't have too much effect on them because they run them far too often as it is! Fact is, if they run it 30 times less frequently, the impact on you server decreases by a factor of 30. With this plugin, villagers will only run one operation per 30 seconds by default - but this is configurable.

    Installation and configuration
    To install the plugin is simple: download the jar, place it in your plugins folder and reload or restart the server. This will generate a folder called 'VillagerOptimiser' in your plugins directory. Inside is a config file which allows you change the time between pathfinding operations, as described above.

    Please note that this plugin requires 1.14.2 or higher. It specifically requires a patch that was released on the 19th of June, 2019 - so make sure you are using a recent 1.14.2 build or a higher version.

    Metrics: We use bStats to collect some (non-identifying) data about servers using this plugin. You can opt out by editing the config.yml in the bStats directory of your plugin directory.

    You may also want to try the plugin SAML. This can help you to further reduce lag from mobs on your server, and it works just fine with this plugin.

    As listed on Simple Anti-Mob Lag. An excellent resource. This resource additionally cut down a lot of primary issues with why our performance continued to degrade.

    VillagerOptimizer has helped a lot to improve the performance in the last months. Thanks for the valuable contribution in difficult times! Now VillagerOptimizer has been replaced by much more effective paper patches and it is time to say goodbye.

    Fantastic plugin. Running a 1.15.2 server and my friends and I built a town bustling with villagers. Without this plugin, it was running at 11-13 TPS and now it's at a solid 20. This plugin may not be as effective as it was in 1.14 but it is super effective in larger scales. Fantastic job

    Very awesome plugin! Very usefull for survival and semi-vanilla server where is a lot of villagers for example our server went from 10TPS to 20TPS

    Very simple config. Recommended by many to reduce those pesky villagers. Running a 1.15.2 paperMC server, and this definitely keeps them from lagging the server as bad.
