The Bach is okay, but really fast and I get really bad cramp in my hand playing it.
If you are getting cramp in your hand with the Bach, then you may have a technique issue that needs addressing.

I'm doing the Bach Allegro Assai which my teacher thinks should go slowly.
It should be lively, but
not fast.

Its interesting that your teacher said to play the Bach slower, my teacher played it pretty fast.
On a modern violin with a modern setup, you can play it at any speed you like, but.......

My teacher also said to play the Allegro Assai a lot slower than I expected. Still fairly fast, but I was trying to play it at the speed that Arthur Grumiaux plays it on the recording I have, and my teacher slowed it down quite a bit, much to my relief!
......the problem with modern interpretations is that most of them are on violins with a modern setup. The bridge is higher, the bass bar much bigger and longer, the strings are a higher tension, a modern bow plays at a higher tension and as a result the instrument responds a lot faster than a Baroque violin. Therefore, the music can be played far faster than it would have been in Bach's day. That's not to say that music was played very slowly back then, it just wasn't taken at the break-neck speeds soloists use today.
Not always possible to do, but the best way to know what speed
Allegro would have been played at, is to play the music on a Baroque violin with a Baroque bow. With a lower tension bow and unwound gut strings, the instrument is much slower to speak and it takes a little more work to produce the notes.
