Difficulty and shares

[Xyver]

When the difficulty goes up, and you're mining in a pool (I work with Bitminter), are the shares harder to get, or do you need more shares to uncover a block?

The pool needs more shares, a share is usually defined as difficulty=1

What is the benefit for the miner, of increasing the dificulty in a pool? I am part of a pool that allows me to set my own difficulty.

Increasing your personal difficulty doesn't benefit you much, with the exception of lowered bandwidth.  Going from Difficulty 1 to Difficulty 2 will cut your upstream usage in half.  From 2 to 4 will cut it in half again, etc., etc.  Downstream bandwidth has a minimum amount due to work notices from the pool, but depending on your rate of share submissions, higher difficulties can also reduce that bandwidth utilization significantly as well.

There's probably some *extremely* minor benefits of higher difficulty due to miner overhead, and some earlier ASICs/firmware versions had problems when mining at lower difficulties due to the rate of share submissions.

can anyone explain me something about difficulty..
for example. i have 10 GHps miner, will i have profit of increasing shares difficulty(from 1 to 2 or 4)?

if you increase your difficulty you will cut down on the amount of traffic you send over the Internet and the amount of time the pool has to spend interacting with your miner. The pool will compensate you for the increased difficulty by giving you more shares for each found hash that you return.
