If someone rewrite code, will speed increase?

I don't know, but I would love to try.
Can someone send me the source code?

On a 32-bit system, each process is given 4 GB of virtual memory to play with, which is separated into 2 GB of user space that the application can actually use at a time.
Not only does 32-bit have a hard limit for the amount of memory it can address, there's also another problem: your devices, like your video card and motherboard BIOS take up room in that same 4 GB space, which means the underlying operating system gets access to even less of your RAM.
Windows expert Mark Russinovich found that a desktop running 32-bit Windows with 4 GB of RAM and two 1 GB video cards only had 2.2 GB of RAM available for the operating system—so the bigger and better your video cards get, the less of that 4 GB will be accessible on a 32-bit system.

By saying "use 3 cores" do you mean that's what happens when you set
wieferich_threads=3
in wwww.ini ?

Yes, I always had 2 before.

CPU/GPU utilization: 1.96 (cores), 0.78 (devices)
Looks like I could try 2 instances or see what happens if I tell this instance to use 3 cores instead of 2.

CPU/GPU utilization: 2.33 (cores), 1.00 (devices) is what happens if I use 3 cores
21.07M p/sec

Then how about a rematch of Wieferich? Now that I know about wwww.ini I can really participate.
Composite started it, and I followed up. We now have a better idea of blocksize.

And just for fun... let's blame the hardware for poor performance (1152 CUDA cores).
