I tested this python compare script. I only added the time output. Here are the results:

aprox 2 hours 15 minutes for 50k pubkey comparison , script generate addition in 200 pubkeys, total 10 million keys generate from 50k pubkeys, to verify
remember its simple addition, but for each key from 50k pubkeys,
here problem is python, uses 1 by 1 thread,
if this same tool in cuda would be done in 2 seconds
or maybe tool in c maybe do it less then 10 minutes
any c or cuda developer can help us to write such tools, for further research
thankx
Hello i have write a custom Cuda library for point addition , multiplication etc (adapted from Jean Luc Pons one)...the use of pycuda (python) to launch the kernel is possible
But can you explain what the purpose of the script you want to made?
Because the speed of point addition can be around 1Gigakeys/sec, only if you work with pubkey loaded in ram
the main problem of what you want to do will be the speed bottleneck of writting the result in a file on the HDD (1Giga Key are more than 32GB of size on the HDD)
So you can compute 1Giga Key in one sec with the GPU.but you will spend 20/30 seconds to write the result
