Francium is a Forge optimization mod that replaces some Random fields with ThreadLocalRandom for better performance and higher fps.
This is inspired by Faster Random (But Francium doesn't change world generation or other stuff that makes huge difference from vanilla. The only difference so far is the speed of squid tentacle movement speed initialization lol). However, Francium's implementation is wider and more rooted.
ThreadLocalRandom has a property: its setSeed method is not a supported operation, Thus, as long as a Random field is not calling setSeed, Francium can replace it with ThreadLocalRandom.
Client side: Optional
Server side: Optional
The below benchmark is outdated due to the security improvement in 1.0.0.
Details: In Francium 1.0.0, To completely avoid the UnsupportedOperationException crash (and this is the only crash Francium may cause) of `ThreadLocalRandom#setSeed`, I did some security improvement so that if a Random field is setSeed, next it will no longer call ThreadLocalRandom.
For players, this security brings down performance improvement for a little bit, in my test my fps improvement dropped to 100 from 150.

You can see my play time is 4:29 below, and in these 269 seconds, I have never moved or change my mouse too much (almost completely still).
This has been tested for three times, and the images below are from the third test.
Average FPS: 780 ~ 800
Average FPS: 630 ~ 650
Not currently.
In 1.19.2+, Mojang overhauled random number generation from Java's own Random to a custom RandomSource class.
So if Francium is to support higher versions, it may only be able to undergo simple replacements (Also, the new effects from this replacement is not at all guaranteed to be consistent with vanilla, which is what Francium didn't want.) in specific classes much like Faster Random, and may not be conducive to fundamental reforms like it be in 1.16.5 and 1.18.2, optimization will also be much less effective.
