another fast c105
Code:

for this one I used your polyselect params, but slightly different sieve params:

Code:
tasks.lim0 = 750000
tasks.lim1 = 1200000
tasks.lpb0 = 26
tasks.lpb1 = 26
tasks.sieve.mfb0 = 52
tasks.sieve.mfb1 = 52
tasks.sieve.ncurves0 = 11
tasks.sieve.ncurves1 = 16
tasks.I = 12

tasks.sieve.qrange = 5000
tasks.sieve.qmin = 100000
 tasks.sieve.rels_wanted = 5700000

Could be an outlier, so we need moar data!
