Re: LS 4.1 too much CPU in the background

The 4.1.1 nightly does not address this issue. We have not found out what causes the increased CPU load since the code involved was not changed since 4.0.6. It must be a side-effect of an other change. Network Monitor receives notifications about all connections regardless of the filter state. Even ...

Re: LS 4.1 too much CPU in the background

This is a different issue. You are primarily seeing a high CPU load on Little Snitch Daemon, probably due to a high rate of DNS lookups. Optimizing this part of the code is on our to-do list.

Re: LS 4.1 too much CPU in the background

ACK, I can reproduce this. Strange, though, because we did not change anything in the code responsible for this. A spindump reveals nothing unusual, so we'll have to dig deeper...

Re: 4.0.3 has huge memory and CPU footprint in High Sierra

Thanks a lot for the diagnostics report! As far as I can tell, there must be a problem with your graphics driver. This may not be directly related to your memory issue, but it's impacting responsiveness and performance of your computer. In the LS Daemon logs, I can see tons of messages like this: 20...

Re: 4.0.3 has huge memory and CPU footprint in High Sierra

When it "quit unexpectedly", it leaves a crash log in ~/Library/Logs. You can view it with Console.app, or it's included (among lots of other info) when you send us a diagnostics report. You can do so by following these steps: • Open Little Snitch Configuration • Click “Help” in the menu b...

Re: 4.0.3 has huge memory and CPU footprint in High Sierra

You make a snapshot of the current connections window by hitting Cmd-D or by choosing File > Make Snapshot from the menu. You can save and load snapshots. This feature can be used to analyze something without hurry. Since you did not know about it, it's probably not the cause. And I have just tried ...

Re: 4.0.3 has huge memory and CPU footprint in High Sierra

Sorry to correct myself: I just wanted to write down what we've found out. And I found a very similar bug description there. Network Monitor does not deallocate snapshot windows. If you make a snapshot of a window (or probably also if you load one), the window (and its memory) is not freed when you ...

Re: 4.0.3 has huge memory and CPU footprint in High Sierra

Thanks a lot for the new vm statistics! I can see that the old block of 822M from last time is still allocated, but it moved a bit and has grown by ca. 1 MB. It's now allocated side-by-side with CG image blocks, so it must have been allocated by something which creates Core Graphics Images. The larg...

Re: 4.0.3 has huge memory and CPU footprint in High Sierra

Don't know. Maybe let it grow even further and then compare the memory maps to see what was added.

Re: 4.0.3 has huge memory and CPU footprint in High Sierra

Unfortunately, the diagnostics is not too informative. I can see that most of the memory (more than 800 MB) is allocated in one chunk. The chunk is from VM_ALLOCATE. This can be pretty much anything. Assuming that the memory is assigned in sequential order (which is somewhat reasonable), we can draw...

Re: 4.0.3 has huge memory and CPU footprint in High Sierra

The objects we know of account for a couple of megabytes. That's definitely a few orders of magnitude less than the amount of memory reported by Activity Monitor. Can you please open Activity Monitor to find out the Process ID (PID) of Network Monitor and then open a Terminal window and typ vmmap PI...

Re: 4.0.3 has huge memory and CPU footprint in High Sierra

When memory consumption is high, can you please first open Console.app, select your device under "Devices", enter "Snitch Network Monitor" as a search term to reduce the amount of log messages to the relevant ones. Then open a Network Monitor window and hit Cmd-Option-Ctrl-Shift-...

Re: Rules that disappear

Reinstalling the old version, rebooting, etc. is somewhat time consuming, so I understand if you rather want to avoid that. 4.0.6 is the current stable version available at https://obdev.at/products/littlesnitch/download.html. You say that the configuration.xpl from the backup cannot be read? Now th...

Re: Rules that disappear

Do you have backups of "/Library/Application Support/Objective Development/Little Snitch/configuration.xpl"? If you have, and if you have some spare time, can you please go back to 4.0.6, restore the backup (using Little Snitch Configuration) and check whether the rules are actually there?...
