- [`gm_addon_optimization_tricks`](https://github.com/CFC-Servers/gm_addon_optimization_tricks) Tips & Tricks to make your addon slim and fast

- [`gmod_random_patches`](https://github.com/Pika-Software/gmod_random_patches) A kit of in-game fixes not affecting gameplay but making the game more productive and fixing some bugs.

<sup>Most of the patches are already in the repository, but I thought it would be worth adding this as well.</sup>

- `cl_limit_render.lua`
  - Disables the HDR player hardware. (High Dynamic Range)
  - Disables Pixel Shaders 2.0/1.4 and Vertex Shaders 2.0
  - Sets the maximum available DirectX version.

- [`Hook-Library`](https://github.com/Srlion/Hook-Library) This is a simple, realible, fast and optimized hook library for Garry's Mod. It's well tested and will not mess anything when added to your server. It can/should improve your server performance.

- [`BadCoderz`](https://github.com/ExtReMLapin/BadCoderz) "Find unoptimized gmod addons and KILL the devs who made them"

- [`Simple-Render-Distance`](https://github.com/scuroinside/Simple-Render-Distance) Addon that allows you to change render distance of certain categories of entities on your server

- [`gmod-lua-performance`](https://github.com/OverlordAkise/gmod-lua-performance) A simple comparison of performance optimizations for gLUA
  - These are a few benchmarks that are tested on a Garry's Mod Server idling with DarkRP with only 1 player online. Some of those benchmarks, if possible, were also tested in a LUA5.3 console on Debian 10. If not otherwise stated differently all tests have been done on a gmod server on linux.

- [`gmsv_async_stdout`](https://github.com/WilliamVenner/gmsv_async_stdout) This is a Garry's Mod server module that moves `-condebug` file I/O out of the main thread, which should significantly improve performance for noisy servers.

- [`gm_microoptimisation_war_crime`](https://github.com/WilliamVenner/gm_microoptimisation_war_crime) This attractively named repository contains a Garry's Mod module that performs a micro optimisation that makes use of LuaJIT's constant folding on all Lua scripts.

- The module intercepts the loading of Lua scripts and preprocesses the Lua code to replace all instances of `SERVER` and `CLIENT` with `true` and `false` depending on the current realm.

- `sh_disable_widgets.lua` Disables unnecessary widget hooks that no one ever uses.

- `sh_limit_phys.lua` Changes the physics of objects, both for the server and for the client.

- `sh_nw_to_nw2.lua` "I don't think this is a good idea for now, NWVars2 have some problems right now which need fixing before this can be even considered."

- `sh_remove_ents.lua` Deletes entities that are not normally used. I think it's worth checking if you're using any of the list.

- `sh_remove_hooks.lua` Deletes hooks that. Also check if you need to.

- `cl_remove_ragdolls.lua`
  - Starts a timer to delete all ragdolls and objects on the client side.
  - Disables the unnecessary depth display hook after death.

- `sh_umsg_to_net.lua` Forces the obsolete umsg library to use the new net.

- `sv_animation.lua` Disables server-side movement of the mouth and ears.

- `sv_run_commands.lua` Runs a bunch of commands to optimize the client and its graphics. Some idiot wrote this, but it seems to work.

- `sv_seatsoptimaize.lua` Makes corrections to the seat network?

- `cl_fontcache.lua` Caches fonts and prevents them from being overwritten without changes.

- `cl_blink_gc.lua` "This addon will check your client's current LUA memory and if too much memory is being used, will manually call for a collection of unused memory." [BlinkGC](https://www.gmodstore.com/community/threads/5532/page/1#post-38589)
  - Reduces the amount of crashes you have due to bloated addons.
  - Gives information in your console about your Active LUA Memory.

- `simplegc/sh_simplegc.lua` Regularly adjusts garbage collector behavior to reduce performance overhead. [scuroinside/snippets](https://github.com/scuroinside/snippets/blob/main/simplegc.lua)
___

Here are just some observations that might help you.

- In ./srcds_run - find the lines `ulimit -c 2000` and replace it with `ulimit -c unlimited`. This will allow us to use more resources and remove some segmentation errors.

- You can play with the values in `server.cfg`:
  ```cfg
    mem_max_heapsize "2048"
    threadpool_affinity "4" // 8 for octa-core, 6 for hexa-core, 4 for quad-core, 2 for double-core
  ```
  
 - Startup parameters:

`-high` High process priority

`-novid` Disables video decoding function - disables codec, not splash screen, does not affect video work directly in the game, - the effect on fps is negligible

`-malloc=system` Allows you to choose the size of memory blocks = loads the RAM, offloads the CPU

`-swapcores` allows you to change threads for materials

`-softparticlesdefaultoff` Disables particle depth filter - gives fps boost, reduces quality of particles

`-gl` or `-r_emulate_gl` Simulates OpenGL on Windows - high fps boost, does not work for everyone
