挖Monero (XMR)新手請益 - 數位貨幣

因為手邊有幾台閒置電腦，又不需要付電費，
所以昨天開始研究挖礦這回事QQ

因為我的電腦只有CPU是 Intel i7 5930k (OC 4.5 GHz)，
顯示晶片是主機板內建，
所以就找適合的CPU挖礦方式。


一開始是用minergate挖(Monero)XMR，
他預設副挖是FantomCoin(FCN)，
但我發現效率實在太低了，
雖然圖形介面顯示的速度是 320H/s，
但我用三台電腦挖一整天，只有 0.005 XMR，
換算下來平均一台的速度只有27H/s，
但是過程中我有觀察CPU使用率的確是600%沒錯(六核心)。


後來想不知道會不會是軟體的問題，就想換一個試試看。


我用另一台Intel i7 3930k (OC 4.5 GHz)的電腦測試，
完全依照https://www.monero.how/tutorial-how-to-mine-monero的教學，
參考"Mining Monero on Fedora 24 and above"那一段完全照做，
從下載到compile好程式都沒問題(我的OS是Fedora 17)，
未更動configure和其他任何檔案，也申請好mymonero的錢包，
pool就選擇依照上述網頁範例的"pool.minexmr.com:4444"開始跑，

但是過程中卻不斷的出現
Stratum connection timed out
Stratum connection interrupted

雖然每個job完成時顯示的速度都有330H/s左右，
但是我在http://minexmr.com/#worker_stats
看到的平均速度只有30H/s左右，
我懷疑timed out的原因可能跟防火牆有關，
我查到minexmr.com有支援很多不同的port，
因此我改用pool.minexmr.com:80來跑，
的確就沒有在看到timed out跟interrupted的訊息了，

但是，雖然每個job完成時顯示的速度約328H/s，
但我在worker_stats看到的平均速度仍然只有225H/s，
不知道有沒有高手可以幫我猜看看問題到底在哪?
非常感謝。


我下的指令為:
./minerd -a cryptonight -o stratum+tcp://pool.minexmr.com:80 -u 位置 -p x -t 6
