Internet speed drops when an application is running about neardrop

[jesuslopezxing]

Stop treating the developer like a machine that works for you, you are not even paying for anything here. Don't forget that anyone also could open PRs to fix it.

@grishka I think you are not able to reproduce it because of your network speed is already on the limit to the speed during the bug. If you can get somewhere a faster connection maybe you can reproduce it.

[macmanjimmy]

Oh, so there is now a bug of sudden... typical

[macmanjimmy]

@ Geisha

whoa.... easy on the language "Comrade", no tears in your "Borscht"

[macmanjimmy]

jesuslopezxing : Not treating the Developer like a "Machine". Its about taking "Ownership" of an issue the developer has a duty to do for its users.

There are numerous reports of issues, and the developer denies it ? he is using a "special" mac we dont have ? LOL

Its about accountability

[grishka]

Can you try this build to see whether it fixes anything? NearDrop.app.zip

[grishka]

Maybe there is, maybe there isn't. We don't know until someone could both reproduce this issue and debug it. So far I've only seen people complain with the "fix your crap bro" attitude, with no attempts whatsoever made to pin down the cause.

[macmanjimmy]

pushback, again typical

[davystrong]

@grishka just want to say, thanks very much for sharing your project. Don't let someone's ingratitude stop you doing that! It's great.

[davystrong]

@macmanjimmy any chance you could try to debug this issue? Set up Xcode, set up the project, try to run it. A tool like Wireshark might help you find what is happening and you could report it here or, better yet, find a solution. It would be very helpful to anyone trying to solve the issue and significantly reduce the time involved, plus it would be an opportunity for you to contribute to a very interesting open source project.

Looks good.

Can you post evidence as to the app being responsible for this change?

[jesuslopezxing]

I have been able to reproduce the same issue. With the app running my speed average drops from 400-500 to 100-200. I have done several attempts.

[macmanjimmy]

Have the Same issue, this classifies as a "pattern" set as a "Login" app now have to start and quit manually....

Neardrop on 116mps off 590mbps

[grishka]

IDK, I can't reproduce this problem. I pay for 200 mbit, I get 200 mbit.

NearDrop just running shouldn't affect your network speed. The only thing it does is listen on a TCP port for incoming connections (that's fully passive) and advertise a service via mDNS (a.k.a. Bonjour, how Apple calls it). The mDNS part supposedly only responds to broadcast packets that Android devices send when looking for receivers, otherwise doing nothing. But that's implemented by the system, in the daemon called mDNSResponder.

is the app running at the same time? running 13.2.1

Created a "NEW USER" account no other apps running/ fresh OS same result

Im paying 500mbps, Blessed to get close to 600, but drops like a rock to 116mbs definitely an issue

How about you fly me to Alaska we can meet there and i can show you LOL JK.

Seriously the app needs work, worked at Apple Tier2 before i became disabled and would not bring this issue to light unless its valid...

You running OCLP what year is your Macbook?

[jesuslopezxing]

OCLP

I don't know what it... I am running 14" M1 Pro 2021

[macmanjimmy]

then you not Running it LOL its a bug... developer just needs to recognize and fix it.. we'll see...

I just run and quit when i need it.. app has a serious leak

[adrianbj]

I am also seeing a significant speed drop!

[macmanjimmy]

awe, everyone except the developer, interesting LOL have to launch and quit each time I use it..

[davystrong]

I'm experiencing the same issue, however, I'm at the limit of my WiFi range, so it's happening at lower speeds: I get about 32 Mbps, dropping to about 17 when I open NearDrop.

[grishka]

The license for this app explicitly says that nothing is guaranteed. I'm just putting this stuff out there for everyone to use but I have no obligations whatsoever.

If you want to debug this problem, go for it. Pull requests that fix bugs are welcome too.

[grishka]

Acting entitled as fuck again, typical

[macmanjimmy]

if you're experiencing drops in your bandwidth, just remember to quit after use.

DO NOT USE this app as a "Login item"
Since the developer (obviously) will not correct this bug, this is the method we have to use...

[grishka]

whoa.... easy on the language "Comrade", no tears in your "Borscht"

If you want to bring out my Russian-ness, then I have to say that we have a term in our internet slang for the state of mind you're experiencing — "пукан бомбанул". I encourage you to do an image search for this.

And, @davystrong is right. Go get Xcode and Wireshark and try debugging the thing that makes you so upset. If you manage to fix it, or at least determine the cause, we'll be thankful.

[unnamed777]

Probably my issue is related to this one. When the app is running, I observe increased network latency. It's visible everywhere, even when I ping a router:

I suppose it could be caused by wifi scanning. Topic with similar issue https://developer.apple.com/forums/thread/97805

Shhhhhh "Developer" is sensitive

[grishka]

When an Apple STA is coordinating peer-to-peer Wi-Fi work

That's an interesting clue. I just did a packet capture on awdl0, the interface for Apple's proprietary P2P Wi-Fi extension, and there are some MDNS packets when NearDrop exits and launches. I'm not sure about the specifics of how MDNS works, but maybe there are network configurations when this happens more often. Now I need to find a way to only advertise my MDNS service on specific network interfaces to test this hypothesis 🤔

Also why the hell did I do this?

Shhhhhh "Developer" is sensitive

Have you downloaded Xcode yet or are you just going to keep feeling entitled to other people's work for free while being entirely unhelpful?

[grishka]

@macmanjimmy иди нахуй 😘

[adrianbj]

@grishka - looks good here also. Thanks for all your hard work on this - such a useful utility 👍

[jesuslopezxing]

Can you try this build to see whether it fixes anything? NearDrop.app.zip

Tested here too and looking good. Thanks!

[davystrong]

Tested and seems to work here too. Thanks!

Not working for me... I can see my M1 Mac mini from my Samsung phone but nothing appears in my mac after trying to send a file...
