ZeroNet\core\tools\tor\tor.exe is using 20% of the CPU

[slrslr]

Step 1: Please describe your environment

• ZeroNet version: 0.6.2 rev3502
• Operating system: W10
• Web browser: FF beta
• Tor status: available
• Opened port: no
• Special configuration: --multiuser_local

Step 2: Describe the problem:

Hello, it is not rare when i see the ZeroNet\core\tools\tor\tor.exe is using roughly 20% (it is sustaned usage for like 15 minutes i am watching the process) of the CPU in Task manager and System Explorer.

Connections (195, total made: 23784)

The normal Tor.exe process probably launched by Tor browser that i am also running is not using any CPU.

Computer is recovered from sleep mode, if it can play any role.

Similar amount of CPU (20%) is using Firefox and sometimes also qBittorrent. It is strange that just Tor would need that much. I seen connections of the process in /stats page and in System Explorer and it is not large amount. I am not browsing ZeroNet atm, i have 250 sites, maybe more in the list. ~126 connected on newsfeed.

After trying to restart the tor.exe it not started so i clicked to update Zeronet and after start the tor.exe is using like 5% of the CPU which is OK.

I think it's depends on the guard node: if it's finds you suspicious then it will require proof of work from you. You can try lower the --tor_hs_limit setting, maybe creating hidden services is the trigger for this.

@HelloZeroNet What is the tor_hs_limit variable? What is the default value / which value i should try? I found someone used value 100

[HelloZeroNet]

The default is 10, It defines how many hidden service (.onion address) will create on startup. I would try to set it to 1. https://github.com/HelloZeroNet/ZeroNet/blob/master/src/Config.py#L263 The higher number increase the privacy by serving different zeronet sites using different hidden services, so it makes it harder to find out what other sites you serving.

@HelloZeroNet

so i updated to rev3504 and started ZN like this: C:\ZeroNet\ZeroNet.exe --multiuser_local --tor_hs_limit 1 And i see in process properties that the cmd is: "C:\ZeroNet\ZeroNet.exe" --multiuser_local --tor_hs_limit 1

Now a few minutes after start i see on /Stats page:

Tor hidden services (status: OK (1 onions running)): global : hereaddress

Connections (97, total made: 582): here are 57 .onion addresses

one hour later i see CPU usage of the ZeroNet\core\tools\tor\tor.exe is still around 20%

Tor hidden services (status: OK (1 onions running)): global : hereaddress

Connections (322, total made: 7468): 242 .onion connections
