• Related to [FEATURE] Reduce latency to create first row ( initial table generation time) #56

I was trying to make the startup time faster and one thing I figured I could do is stop copying strings during text pool generation.

However I made the change to avoid copying and it doesn't really seem to have helped, but I figured I would put up the PR in case someone else was interested
