thank you man this addon is extremely helpful

There should be a way to target specific hooks with this addon, preferably in the form of another argument

Hey! Thanks for the love!

hey so i love u for this

I made it specially for you in the first place! 😉

this has been very handy, thank you.

Greetings!
Your case is a little special. As mentioned in the messages, the errors come from the conflict finder, not the lag finder. Please retry the lag finder after uninstalling the conflict finder. I'm sorry for the inconvenience.
It seems that there is a special case where the conflict finder tries to send information, but for an odd reason, it seems that the information is too large, and that is surprising to me!
Well, good point here: the conflict finder needs to be fixed to handle this special case where there is too much information about the location of Lua files. I did not expect this!
The message about the not found hooks for event "1" does not give me any ideas BTW.

It stopped working for me.. it pops me "Could find no hook with event name "1"!

where do I find the hook here?
and what do I type in the command?

Yes! Thank you!

most usefull addon EVER

God blesses me constantly, yet thanks for the appreciation! xD
I'm very glad to be helpful sometimes. Incompetent but somehow useful. 🤪
It's great that this add-on still works because I have not updated it in ages.
You actually are the good one: you make good use of Garry's Mod. 😁

Day to day im suffer from stutters, at least i have good fps like 60+ on big maps and 100+ on small. Yeah, i got like 200-300 addons, but people have more and their Gmod runs good. Stutters everything, mostly like from sound caching and do thing that causes small scripts.
And i found this. God bless you, bro. Using your addon, i found these piece of sh*t, that create stutters. Addon called "Catmull-rom Cinematic Cameras". Yeah, thats cool addon that create cinematic cams trails, but this addon is also so unoptimized and calls like 200%+ problems, like you addon says, instead of other 0.1-0.2%.. Now i can play like its minded, create some machinima and avoid to re-recording every moment, that game stuttered. God bless you and your family.. You such a cool and smart man, that helps to people find trash and delete this

Well, I don't think that it could help with the memory usage, but I am glad that you could find the add-on that was both laggy and a big memory consumer.
Thanks for the love! ❤

I LOVEE YOUU

OH MY GOD THANK YOU DUDE YOU HELPED ME FIND A USELESS ADDON THAT WAS LITERALLY USING 2 GIGS OF RAM

Was easy mate! Thanks for being my user.

This tool is so damn useful, you are a KING.

Thank you Rib!
SuperDean, sadly, the LuaJIT implementation included in Garry's Mod does not seem to have a memory allocation tracing feature, in the same fashion as tracemalloc on Python. Such a feature would have to be enabled through a function or a command line argument, because it involves a performance penalty. I did not see anything like that in Garry's Mod.
Things that do not belong in the Lua world should be monitored too. If you are looking for memory usage issues on the game version of Garry's Mod, then the biggest memory eaters are models and textures, from what I guessed. Maybe fonts could be problematic, particles, sounds? Sadly, Garry's Mod does not make it easy to know what has been loaded.
The server version also seems to load certain things they should not, like material animations for just one random example.
Also a friendly reminder, the game version of Garry's Mod eats way less memory in its 32-bit edition.

is there something like that tells you what addons uses up your ramm instead of cpu?

Invaluable addon, thank you!

Well, if there was no Lua errors at startup then the add-on just was not mounted properly. No update was done in a long time.

still works as of now for me

Tried to run this singleplayer an d multiplayer, says "unknown command" in the console.

BTW, don't stop the test when there are still players in, because TTT2 would overflow the channel again.
If I'm correct, the test ends when the player who initiated it leaves the server, which makes sense except in this case. It would be cool to reconnect with the test still running. Honestly this is something I should consider doing.

Hi, thank you!
Wait, you must have used find_laggy_hooks_sv from the client's console. Have you tried it on the server's console instead? (I don't think it can help when players are present.)
Here is a trick that should work: start the test from the server's console right after a map change, but make sure to do so before any player has finished loading. Of course you can do the same when nobody is connected.
Sadly, I think the only way to fix this from my add-on would be to slow down the startup by adding more and more things to the test instead of immediatly adding everything.
TTT2 might have less complexity in limiting the number of sent messages, but I guess it does not make sense to the creators, even though it's literally the responsible add-on for this issue.

Hehe, I proved again to be incompetent! 🤡

This mod is a great debugging tool. Sadly I found that it doesn't seem to be compatible with the popular TTT2 mod. When it's used, the session crashes due to stack overflow.

"[TTT2] Trying to hotreload weapon_ttt_detective_cube .
[TTT2] Hotreloading weapon_ttt_detective_cube was successful.
[TTT2] Trying to hotreload m9k_striker12 .
[TTT2] Hotreloading m9k_striker12 was successful.
Lag test started, next output in 30 seconds!
Dropped fskin from server (Client 0 overflowed reliable channel.)"

It's due to TTT2's way of announcing the hotreload of every active addon that overflows the console. I'm not sure if it's possible to fix it...

Hehe, thank you!!! I created this tool because I could not stand not knowing where lags come from, and I was asked so much if I could inspect servers etc. I'm so glad it's been so useful to many other people! ❤
Thank you all for your heartwarming comments!

best. debug mod. EVER. thankyouthankyouthankyou. why this type of function isn't in the base game in some form is beyond me. such a lifesaver, have the silly steam award as a thanks

Hey Deno,
Wow, this comment is so expressive and super sweet! Thank you very much, I'm so glad I could help you! You too are a gentleman for dropping such a great comment! 🤍

I must say kind sir, your addon saved my buttocks. I almost commited punching a frickin hole into my pc, but as I saw your addon that did indeed save me from allot of trouble, I couldnt simply resist but had to write this flabbergasting comment on it. You gentleman are truly a hero because I almost executed all my addons that were innocent. I wish you a very fabulous day.

Ouch! 😭

people also like fancy text and addon names, with capitals on the name, for example: "Addon Lag Finder", it is simpler but more people will see

That's why it's good to remember to share decent addons like this one with your friends

Yeah but there is also the keyword-based relevence that plays into that! It is so disappointing. I must have done something wrong.

the steam workshop algorithm only gives attention to newer content, if your addon does not blow up in the first days it never will

I'm so sad that it's not easier to find. I don't know what to do to improve the way it shows up in search results. 😢

i was looking for a mod like this for more than a year, i finally found what i was looking for

Hehe, you are welcome! 🇫🇷+🇮🇹=

Thank you my french friend, you saved me many headaches! Love from Italy

Just start the test (no required arguments) and read the periodic output. The results the most near the top are the most laggy hooks. If there is a lag, make sure it happens, so you can see it on the output corresponding to the period of its occurrence.
If you specify a single argument "0", you stop the test.

im kinda confused because idk how should i use it in gmod console

perfect

Thank you guys so much for the appreciations!

This is an amazing tool and should have 5 stars.

I run 600+ addons on a server with friends, so to easily find the culprits of the worse addons for performance makes everyone happy.

Good job man

This addon is amazing, I was having 15fps with lag spikes leading to less than 10 fps on a decent rig in most maps. I ran the commands to find the culprit (In this case it was an old SWEP more than seven years old), and after removing it and reloading the map my FPS easily shot up to 60+. Thank you so so much!!!

Thanks!

A frame lasts a given duration, for example 16.7 ms if you get 60 fps. It's basically the ratio of the hook duration (the sum of all the times it was called during a frame) over the frame duration. But if I remember correctly, I added some fancy calculation to compensate for whether a long time was spent during a single frame (noticeable lag), or if it is run like on every frame without spending a huge duration every time (overall slowdown), to give each case a meaningful impact score. And yeah, that explains why sometimes the impact is over 100% percent.

what does Impact mean? it's displayed as a precent for some reason.
