Hi, I'm getting rather frustrated with the lack of speed for simple arithmetic in number fields. At the moment, I'm most interested in very fast cyclotomic fields. (A comparison is in the P.S. to get a feel for it). After some profiling and fiddling around a bit, it appears that the lack of speed is caused by little bits here and there. Probably the biggest hit is that the polynomial representation is not stored in PARI format internally.
It appears to me that they really need to be moved to SageX and then optimized more aggressively. Is PARI the best tool for the internal format? Will this just be moved to FLINT later or will that be utilized through PARI? Any other bits of advice for a move to SageX in this part? And, just to make sure, no one else is already working on this are they? -- Joel P.S.
