but Even after loading it's still lags. seriously try klogg and log fusion at the same time.

in some ways I'd rather use log fusion as it's more featured but the speed difference is a game changer. ]]> https://www.logfusion.ca/Discussions/View/logfusion-66-much-slower-startup-time/?ID=0d256fe9-46d4-4c4b-9bf2-6d2d03ddfff3#13 Tue, 19 Nov 2024 18:18:05 GMT Binary Fortress Software https://www.logfusion.ca/Discussions/View/logfusion-66-much-slower-startup-time/?ID=0d256fe9-46d4-4c4b-9bf2-6d2d03ddfff3#13 LogFusion A large part of that delay in Win10 and newer is loading the event log drop downs. We'll see if we can make any improvements there going forward.

However, after upgrading to Windows 11, the startup became very slow, even when nothing else was open.

So, I tried downloading versions 5.0, 6.6, and 6.9.1-Beta3, but there was no improvement.

It takes more than 7~13 seconds to see an empty interface.

I tried using dotTrace to analyze the startup time and came to some conclusions,
but I couldn't understand most of them.

I hope the official team can try to reproduce the issue to see if it can be resolved.

The snapshots and flame graphs have been uploaded to the attachment.

My operating system is
Windows 11 IoT Enterprise LTSC Edition,
version 24H2,
installed on 2024/11/6, All Is Empty.
with the OS version 26100.2161.
The Windows Feature Experience Pack version is 1000.26100.32.0. ]]> https://www.logfusion.ca/Discussions/View/logfusion-66-much-slower-startup-time/?ID=0d256fe9-46d4-4c4b-9bf2-6d2d03ddfff3#10 Thu, 19 Jan 2023 16:31:01 GMT Binary Fortress Software https://www.logfusion.ca/Discussions/View/logfusion-66-much-slower-startup-time/?ID=0d256fe9-46d4-4c4b-9bf2-6d2d03ddfff3#10 LogFusion How long does it take to load up when 0 logs are being loaded? ]]> https://www.logfusion.ca/Discussions/View/logfusion-66-much-slower-startup-time/?ID=0d256fe9-46d4-4c4b-9bf2-6d2d03ddfff3#9 Thu, 19 Jan 2023 10:27:48 GMT Binary Fortress Software https://www.logfusion.ca/Discussions/View/logfusion-66-much-slower-startup-time/?ID=0d256fe9-46d4-4c4b-9bf2-6d2d03ddfff3#9 LogFusion Just ran it through procmon again and peered through the debug logs - theres a ton of font scaling related info, but disabling that diddnt change performance noticiablly.

Tried the latest beta too, same issues. Heres a perfmon log. ]]> https://www.logfusion.ca/Discussions/View/logfusion-66-much-slower-startup-time/?ID=0d256fe9-46d4-4c4b-9bf2-6d2d03ddfff3#8 Thu, 19 Jan 2023 10:02:45 GMT Binary Fortress Software https://www.logfusion.ca/Discussions/View/logfusion-66-much-slower-startup-time/?ID=0d256fe9-46d4-4c4b-9bf2-6d2d03ddfff3#8 LogFusion I'll say that logfusion is some of the slowest software to launch that I've experienced,and I use *insanely* fast hardware.
(13900k, p5800x optane nvme (datacenter hard drive with extremely low latency, its somewhere between memory and ssd speeds)
Was trying to poke at it today to see what could be possibly done to fix it, would love some ideas. Have yet to hook it up to procmon or a debugger, but its enoguh that I'm going to start looking for an altenrate software soon if it doesnt speed up.
To note - this slow launch speed is even if it has zero logs to open at startup.

Heres a debug log, including performance metrics turned on.
Unsure why the debug log has so much info about my monitors.

FYI - DisplayFusion tends to be laggy too, I try to not leave it running and just load it when using it to restore/set monitor profiles.

This is with th last stable verison 6.6, I can try the 6.7 beta if you think it would help.

Looks like I already tried running procmon to diagnose the issue last time it annoyed me, for the 6.7.4 beta. - https://www.logfusion.ca/Discussions/View/logfusion-67-beta-4-now-available/?ID=be1bf859-6b4d-4de9-a514-fd94c6b302ea#2 ]]> https://www.logfusion.ca/Discussions/View/logfusion-66-much-slower-startup-time/?ID=0d256fe9-46d4-4c4b-9bf2-6d2d03ddfff3#7 Wed, 18 Jan 2023 23:04:14 GMT Binary Fortress Software https://www.logfusion.ca/Discussions/View/logfusion-66-much-slower-startup-time/?ID=0d256fe9-46d4-4c4b-9bf2-6d2d03ddfff3#7 LogFusion I started off with the stable version before moving to the beta, the issue is there as well. ]]> https://www.logfusion.ca/Discussions/View/logfusion-66-much-slower-startup-time/?ID=0d256fe9-46d4-4c4b-9bf2-6d2d03ddfff3#6 Tue, 17 Jan 2023 16:48:16 GMT Binary Fortress Software https://www.logfusion.ca/Discussions/View/logfusion-66-much-slower-startup-time/?ID=0d256fe9-46d4-4c4b-9bf2-6d2d03ddfff3#6 LogFusion Can you try out our latest stable version and let me know if the issue persists there?

I hadn't used it in a while because it always felt a bit slow.

How much longer is it taking to load up?

Could you send me a copy of your troubleshooting info? Here are the steps:

My team has reported an increase in the amount of time it takes for LogFusion to startup and become 'responsive'. This seemingly happened at the launch of 6.6. I noticed this myself and didn't think anything of it until my team mentioned it as well. Are there any steps we can take to decrease the startup times?

Thanks ]]>
