Ok, you miners can't read:
reduced devfee, it's 2% now (72sec instead of 90sec) if you use secure SSL/TLS connection
After using the SSL/TLS, the share rejection is 1.0 to 1.5% now. The rejection rate was 0.3 to 0.5 previously.
my reject rate, with ssl, is 0.71% and 0.83% on my two rigs. more or less what it was before.
People don't understand that a rejected share is one that cross with a new job somewhere along the way. If the pool is slow processing incoming shares you also may get a reject. My rejects were around 1% at flypool going as high as 3% with timeouts that are frequent there. On the other end at dwarf the reject rate is 0.2%. So before blaming the miner you should be blaming the pool
