I'm one of the people with a very large QDF (460MB) and a lot of transactions (~120K) amassed over the 35 years of usage…. and always looking for ways to speed things up.
I just got a new highly spec'ed HP laptop and in my review of these forums so that I could re-implement all the tricks and hints I realize I have a few up my sleeve that haven't previously been shared. So here goes…
- Open up the Windows Task Mgr, go to the performance tab and start clicking around Quicken (open your most complex investment accounts, portfolio view, etc, while you watch the CPU speed readout. If you're not getting 80 - 90% of your CPU's rated CPU speed, then read on. Quicken is an (old) single threaded process (ie, makes no use of multi-cores) so the speed you experience is proportional to the CPU speed reported.
- Change every power or performance setting you can find to "best performance" and not "battery", "power saving", "balanced" or anything that isn't the highest and most power hungry.
- check Settings/System/Power Mode for the Win 11 setting.
- check your manufacturer's system app (like Lenovo's "Vantage" app) for their own power or performance settings. I found on my now discarded Lenovo laptop that the Vantage settings overruled the Win 11 Systems settings!
- my new laptop is an HP and it has an app called Omen Gaming Hub that boosts performance of games. Within that app, I was able to register QW.exe as a game and select settings such that when Quicken is running the Omen app will boost performance (if you have this available you'll see detailed selections to work through).
The new laptop has a 5.1 GHz Intel ultra core 9 CPU and in the Task Mgr I've seen it get up to the 4.3 GHz range. Overall a step up from the Lenovo it replaced, although I still wait (though not as long) for my big transaction investment accounts to load. Small account registers and running reports are actually quite snappy compared to running on the Lenovo.
My comments / suggestions should be used along with all the excellent suggestions you'll find by searching other threads. Here are two:
