Why different? 360MH/s on GUIMiner = 170MH/s on Deepbit?

[Bitconian]

Hi,
I just started to mine with GUIMiner and I've added 2 pools, Mt.Red and DeepBit. (I'm pretty new on these programs, so please, bear with me ) I also have installed the Miner Status app for android.

So, on GUIMiner, I got:

      Deepbit 360MH/s
      Mt.Red 325MH/s


But on my app I see this:

      Deepbit 220MH/s
      Mt.Red 170MH/s


Also, I checked my worker on Mt.Red and also says 170MH/s.... what's wrong? which one is "lying" to me? My GUIMiner? the pools? the apps?

Its possible the android app is bloatware, uses inefficient algorithms or is written in a slower programming language to a point where it causes your machine to run slower.

Memory and instructions per second (ipc) are both limited resources and monitoring apps which consume a high enough proportion of it can leave less available resources for your miner resulting in degradation of overall performance.

Your hash rates at the pools are estimated based on shares submitted.
So either you just need to wait a bit for the estimate to be updated or for some reason the pools are not getting your shares.

Chances are miner status is not the problem. It just reads from the pool json stats.

Yeah, most sites average your hashrate over say the last 5, 10, 15, 20 rounds.  So if you weren't running full speed for all those rounds then you'll see a truncated hashrate. 

Leave your rig running for a day or two and you'll see a realistic hashrate.
