Some example of one of my machines (Intel Atom):
Code:
[Worker #2 Jul 4 12:50] Stage 1 complete. 1910782 transforms, 1 modular inverses. Total time: 1122.019 sec.
[Worker #2 Jul 4 12:50] Available memory is 4092MB.
[Worker #2 Jul 4 12:50] Optimal B2 is 1017*B1 = 254250000.  Actual B2 will be 254268105.
[Worker #2 Jul 4 12:50] Estimated stage 2 vs. stage 1 runtime ratio: 0.357
[Worker #2 Jul 4 12:50] Setting affinity to run helper thread 1 on CPU core #4
[Worker #2 Jul 4 12:50] Using 3932MB of memory.  D: 19110, degree-2016 polynomials.  Ftree polys in memory: 2
[Worker #2 Jul 4 12:50] Setting affinity to run polymult helper thread on CPU core #4
[Worker #2 Jul 4 12:52] Stage 2 init complete. 123530 transforms, 1 modular inverses. Time: 120.117 sec.
[Worker #2 Jul 4 12:53] PolyG built.  Time: 67.360 sec.
[Worker #2 Jul 4 12:53] M675347 stage 2 at B2=61639305 [16.66%].  Time: 0.000 sec.
[Worker #2 Jul 4 12:54] PolyG built.  Time: 67.692 sec.
[Worker #2 Jul 4 12:54] PolyH built.  Time: 36.737 sec.
[Worker #2 Jul 4 12:54] M675347 stage 2 at B2=100165065 [33.33%].  Time: 0.000 sec.
[Worker #2 Jul 4 12:56] PolyG built.  Time: 67.937 sec.
[Worker #2 Jul 4 12:56] PolyH built.  Time: 35.953 sec.
[Worker #2 Jul 4 12:56] M675347 stage 2 at B2=138690825 [49.99%].  Time: 0.000 sec.
[Worker #2 Jul 4 12:57] PolyG built.  Time: 68.429 sec.
[Worker #2 Jul 4 12:58] PolyH built.  Time: 37.144 sec.
[Worker #2 Jul 4 12:58] M675347 stage 2 at B2=177216585 [66.66%].  Time: 0.000 sec.
[Worker #2 Jul 4 12:59] PolyG built.  Time: 67.681 sec.
[Worker #2 Jul 4 13:00] PolyH built.  Time: 36.372 sec.
[Worker #2 Jul 4 13:00] M675347 stage 2 at B2=215742345 [83.33%].  Time: 0.000 sec.
[Worker #2 Jul 4 13:01] PolyG built.  Time: 69.471 sec.
[Worker #2 Jul 4 13:01] PolyH built.  Time: 36.607 sec.
[Worker #2 Jul 4 13:02] H(X) scaled.  Time: 9.851 sec.
[Worker #2 Jul 4 13:02] PolyF up.  Time: 9.244 sec.
[Worker #2 Jul 4 13:02] PolyF down.  Time: 21.425 sec.
[Worker #2 Jul 4 13:02] PolyF up.  Time: 26.766 sec.
[Worker #2 Jul 4 13:02] PolyF down.  Time: 41.547 sec.
[Worker #2 Jul 4 13:03] gg = mul H(X).  Time: 2.540 sec.
[Worker #2 Jul 4 13:03] Stage 2 complete. 711687 transforms, 6 modular inverses. Total time: 702.843 sec.
[Worker #2 Jul 4 13:03] Stage 2 GCD complete. Time: 0.240 sec.
The resulting B2 is about eight times higher than before. Additionally, stage 2 is about 80−100 % faster now!
