Here are good settings for the current Difficulties if using the 4 Threads.
Code: Select all
Threads = 4 PrimeTableLimit = 2147483648 SieveWorkers = 2 SieveBits = 24
It is about 2.5-3x faster than the Raspberry Pi, and it has similar multicore performance as old Mobile Sandy Bridge i5/i7s with 2 Cores like the 2620M, which is honestly not bad for something based on Atom architectures.
Note: if you plan to buy a similar laptop and plan to use Mobile Data, the Intel XMM 7360 = Fibocom L850-GL does not have drivers for Linux :|
There is a GitHub repository for it, though I prefer to wait for an out of the box support.
