Hi,
thanks for your detailed symptom description and it's very useful to know which apps you use. One of the changes in 19.4 is that we perform deeper cloud analysis of rare files. However, the verdict of that analysis should be cached, so it should only affect the first launch of an app. For example, if I launch Obsidian on my 2.6 GHz Intel Core i7 MacBook Pro, the first launch takes a bit over 10 seconds, but the next launch takes less than one second. Is this consistent with your experience, i.e. is the app launch faster on second launch?
We have discovered some cases where the cache isn't populated properly if this "deeper analysis" takes longer than expected. This is something we will address in an upcoming update.
Regarding LibreWolf, out of curiosity, do you install it via Homebrew or via disk image?
As a result of the deeper cloud analysis, our systems will gather information about various third-party software over time. Once a sample has been analysed by our backend systems, a deeper analysis will no longer be needed. Thus we do expect performance to increase over time as this update rolls out to more users and our backends learns about more software. There are also cases where this deeper analysis doesn't make sense, for example locally built software. For those cases, it may make sense exclude that particular location from scanning. We're looking at ways to detect and improve this use case as well.
Finally, a way to speed things up is disabling deeper analysis, which cone be done in the product Settings → Privacy. The product will still do cloud lookups but not do cloud analysis of unknown software. You can also completely disable cloud malware checks by disabling "Use cloud-based file reputation" in the Viruses and Threats tab. You will still be protected by the local scan engines.
If you do choose any of the above workarounds please let us know. We appreciate the feedback and will improve the performance continuously over time, and your feedback helps us a lot in that regard.

Hi,
Thank you for your prompt response.
So this explains a lot, as I don't experience this.
If I don't have both apps as scanning exclusions, both take a long to start up every time I open them. So I suspect the analysis isn't getting cached.
For Librewolf, I installed it via disk image.
I've already disabled “deeper analysis”, so that hasn't helped in my case.
However, I haven't tried disabling “Use cloud-based file reputation”
I'll try it and see if it helps.
I do hope a future update resolves some of these issues, though, as I do like the product otherwise when compared to what I used previously.

Hi Arthur...
I ran the terminal script, and indeed the hotfix has been installed...
I have to say I have not noticed any improvement in performance...
I suspended F-Secure Safe for 15 minutes, and instantly my computer was back to full speed...
So, I'm afraid it didn't work for me
Regards

thanks for the update! We are currently continuing the work on performance improvements.
We will see if we end up releasing a regular product upgrade or another smaller scoped hotfix to ddress the remaining issues.
We'll provide an update in this thread once we have any news on the topic.
Best regards, Arthur

On my Intel iMac (2019, i7, 128gb memory) I was facing huge performance problems until I disabled automatic scanning (just disabling cloud-based scanning did not meaningfully affect things). Obviously, this is not optimal. My M1 Max Macbook Pro did not face the same problems. Really hoping an update that fixed this can be issued soon..

Hi all,
we have now released a new hotfix for both fs protection 19.5 and F-Secure Total 19.4. It includes numerous bug fixes and other performance optimisations. Feel free to try it out and share your experiences with us.
If you're still experiencing issues we'd be very interesting in getting Support Tool diagnostics with debug logging enabled. Follow the instructions on https://help.f-secure.com/product.html?home/total-mac/latest/en/task_364793A834BD4955AD95837F0E3C3709-latest-en and ensure you reproduce the issue at hand after enabling the debug logs (e.g. if there's a particular app that is slow, use it for a while). After reproducing the issue with debug logs enabled, run Support Tool to gather the relevant diagnostics and share it with us via a DM here or e-mail to beta@f-secure.com.
Note: ensure that you're using the latest macOS version before enabling debug logs. Some macOS Ventura and Sonoma versions have had issues with debug logging, but they should be fixed in the latest releases.
