(litecoin) High hashrate but low amount of submitted shares in solo
The system of shares on a pool is set by the pool owner. It is not exactly the same as mining litecoin solo, and in fact some pools will have much smaller shares (pool-x.eu) set up to encourage you to continue mining, even though you are not actually mining more litecoin. Other pools have larger shares which take longer to mine (ltc.kattare.com), but are actually less work for the server so (theoretically) you should get a bit more from the longer ones.  While solo mining you are A) getting all the shares yourself with no "pool power" and B)getting the normal share size for litecoin. Hope this helps, 5mil
