question: font rendering speed different between sarasa-gothic-ttf-0.8.2 and the latest 0.37.4

Hi, I just test several versions of the sarasa-gothic-ttf font release under Code::Blocks IDE under Win7 64bit, which renders the font in normal GDI mode.

The sarasa-gothic-ttf-0.8.2 version(released in year 2019), such as: sarasa-mono-sc-regular.ttf, the editor renders very fast
The latest release sarasa-gothic-ttf-0.37.4 with hinting version, the editor renders very slow, I can see the whole page get updated when I scroll the page. Though the un-hinted version renders fast, but the font shows badly because some lines of the font may be too trick.
I choose another version such as: sarasa-gothic-ttf-0.16.5(released around year 2021), it also renders very slow.

My question is:
What is the different between those release? I don't see much change logs of each release, but only a git tag about the version number.

The size of the font is also different, for example, the 0.8.2 version of sarasa-mono-sc-regular is about 34M, while the latest 0.37.4 release this same file is about 23M, so why the ttf size is smaller, but the render time get longer?

Thanks.

Another question is:

in the 0.8.2 release, there are two files named sarasa-monoT-sc-regular.ttf and sarasa-mono-sc-regular.ttf. While in the latest release, there is only one file named sarasa-mono-sc-regular.ttf. So, what is the difference between mono and monoT, thanks.

I think one difference is that the newer versions use a more complex embedded instructions to reduce the size. As a result, it may take more time for glyphs' first rendering.

Resolve as by design.
