Launcher takes >1 minute to start on a a modern 6-core processor with plenty of RAM

Still happening. Everything as updated as Windows will allow.

Video, and associated launcher log added

Affects 2.25.4 (Legacy Win)

There is for sure a slowdown with every launcher update as I've seen.
This latest running Armadillo launcher again is noticeably slower at loading times. Do we need to watch this thing run without any indication of actual progress? You know 10%, 59/100, anything.
There are times where it takes around 19 seconds to load. I can restart my system in less time than that, or update my kernel.
I am running the java version of the game on Linux.
Kernel: 5.15.0-112
Processor: AMD Ryzen 9 5900X 12-Core
Memory: 64GB
Graphics: AMD Radeon RX 6700XT 12GB

So my hardware is a bit better perhaps than that of the OP, but it seems to scale. My opinion is perhaps we need less overhead, bloatness, etc. and let players just load the game. Does anyone really care about all of this extra junk info that has to be downloaded when the launcher starts? Maybe move those tasks when someone actually clicks on it to get the latest info.

Hi!

Please, update your Launcher to the latest Beta version and check if the Fix.

For me, the launcher takes only ~3 seconds to launch on my Windows 11 Pro 24H2 machine (Intel Core i7-14700K, 32GB RAM, AMD Radeon RX 570 8GB).

2.27.11 - still takes ~25 seconds to load for me - double what it takes to load 2.1.17784, which itself used to be quicker. Windows 10 i5-7200U.

There should be probably be more thorough testing done but there's a definite issue with declining performance so unless there is a better ticket with more information provided then this one should be reopened.

v.2.27.11-1.7.2 loads in <10s for me at the moment.

I am uncertain if this is because the issue is actually resolved however. My amateur reading of the earlier logs tells me that previous versions seemed to stall for 20s+ waiting on response from the servers for things like storefront data. Currently minecraft.net and other Microsoft websites are loading much faster for me than they usually do, and did when I first reported this issue, so the improvement in launcher startup may be purely from improved performance of the online service at this time. In my entirely anecdotal experience Microsoft online services are very inconsistent for me in responsiveness and load time so in the future performance may degrade again and the launcher startup time along with it.

Significant work was put in to improve performance on the 2.27.11 build. So improvements seen in that build are real. Per our internal testing, loading across different OSs & devices is, on 2.27.11 vs the previous build, 50-75% faster. 

@unknown If you are timing loading time yourself, start the clock from when a window first appears - not from when you first click the icon. The duration from icon click to the window first appearing is more dependent on the speed of your machine. 

Time from when window first appears to when 'Play' button appears:

2.1.17784 - 4 seconds

2.27.19 - 15 seconds
