Working on Windows, I’ve noticed that FontBase has been using more CPU lately, to the point that it’s more than my browser (Firefox). It’s only got a 100 fonts activated. Anyone else experience this?
Hello @koksiroj, thank you for your post and welcome to the forum 
Have you added any new fonts recently? The total number of fonts can influence CPU usage as FontBase constantly keeps track of the folders/fonts added into it.
Thank you again,
Hi yuriy
Interesting Issue. I encountered on my old Notebook (early gen Intel I7, about 10 years old) also a very high CPU usage, but not with my 2023 I7 gen 13 power workstation. Both have the same (huge) amount of fonts and folders installed in watched folders. I dont’t know how fontbase works with CPU cores and RAM. The Notebook lacks with RAM and core speed …

Hello Matthias, thank you for your post
That is a very odd situation indeed. The first thing that comes to mind is the possible difference in the number of cores, but that is just a guess at this point 
Will need to investigate this further, as in theory this shouldn’t happen of course.
I’ve come across some data indicating that this could be related to the Intel driver version, i.e. the updated ones will be more effective at managing CPU load.
Thank you again,
Thank you for your answer. I’ll watch it and maybe write again, if I discover anything new. The old Notebook isn’t that important any more.
PS: chatGPT confirms the causality with CPU generation, SSD speed, RAM etc. 
Regards

Im not sure i noticed before, but today i updated to 2026.4.1 and noticed pretty high RAM usage. Prior to this screengrabs it was 740MB, when i did the screengrab it lowed to 648mb. I dont remember seeing it this high before?
This is on Windows 11 25H2 rs26220.8165
PS there is also an issue attaching images. I could not attach a PNG from a screengrab, says “Sorry, there was an error uploading high-ram-usage-fontbase.png. Please try again.”
Tried converting to JPG, still same error
How many fonts do you have added in FontBase?
Added or activated?
Added is 15542, but active is around 5099.
But on the other hand, that counter doesnt seem correct. I found the numbers high, so I checked files in the folder. It counts 12025, but there are also tons of files not being fonts in there. So how come the app counts much more fonts or does it also count fonts from other areas?
Again, I can’t show because i cant seem to add images. Keeps returning an error.
Checked the RAM again today, now it seems to hover around 300-350mb
