Greetings,

Use --help or -h after your miner . . . example: "cgminer.exe --help" or "sgminer.exe -h"

I am certainly no expert on this, so if I'm off base I'm sure the experts will chime in.

********************************************************

--expiry

Upper bound on how many seconds after getting work we consider a share from it stale

If you are getting lots of "stale shares", try lowering expiry.

********************************************************

--queue  

Minimum number of work items to have queued

Use a low queue (0 or 1) for fast pools or fast solo throughput. A higher queue on fast pools will result in frequent "stale shares".

********************************************************

--scan

Upper bound on time spent scanning current work, in seconds

For solo mining I would stick with the default setting.

If you are mining a multi coin pool that switches coins frequently, a long scan time will increases your work restart time. This long scan time results in reduced hashrate and Pool block errors. If you reduce this scan time, it will reduce your work restart time thus increasing your hashrate.

cgminer --scan-time|-s <arg> Upper bound on time spent scanning current work, in seconds (default: 60)  

sgminer --scan-time|-s <arg> Upper bound on time spent scanning current work, in seconds (default: 7)
