I have a strange issue, when I am mining on 3x 6970s with Deepbit the speed fluctuates from 800-1200Mhash but when I tried on Bitclocker it is quite constant at 1200Mhash, is it because of the way the figures are shown?

What figures are you talking about?  The ones on your miners, or on the website?  If it's on the website then yes, each website prob calculates the rates in a different way.

The figures on the web sites, the figures on my machine is pretty stable, that's what puzzles me.

count shares per day, 3 days shares would be even more accurate

Counting shares for more than 24h is a good measure.
Also you may compare actual payouts, but this would require more than a couple of days to average out bad/good luck.

Both seems as good, very tough to choose from Smiley . I think I will mine at Deepbit as it seems to be much more popular.

deepbit updates the hashrate on miner more often than bitclockers, so thats why you could get bitclockers stuck at the highest hashrate reported for longer than it actually is submitting.

What a horrible logic to go by. People mine there because they are clueless
& don't know 3% for prop or 10% for PPS is a rip-off (even if you get reduced variance for the prop. due to massive hash rate).

No offense to Tycho either; Hell I mined there for a long time back when prop. was still viable.

You shouldn't mine at a site which is the most popular but the one which yields the largest profit on average.

The BitClockers hash rate is a 15 min average updated every 5 minutes.

Bitclockers has the most live *statistics of any mining pool.

Think about it, deepbit finds blocks much faster than anyone else. When they find a block, your speed is recounted, and because the shares are still fresh. i.e 15 minutes or more must pass, your true speed is not shown.

Deepbit's luckmeter (user hashrate estimation) is updated once per minute and calculated over a user-adjustable window, so it's even more live than the most live statistics of any mining pool (jk) :)
But this is not affected by finding blocks and no special recalculations occur at that moment, so that's not the reason.

A majority of stats on BitClockers.com are real time for registered/logged-in users.
Hashrates are updated every 5min based on a 15min sliding average.
Failed/inactive miner detection is 5 min.

Public facing data for guests is 1min. Graphs are 5min. Hashrates are 5min.


Real-time is pretty up to date Wink

As for how hashrates are calced on bitclockers:

MH/s = (CurrentTotalShares - SharesLastUpdated)*4294967296 / TimeInSecondsSinceLastUpdated / 1024 / 1024)


4294967296 is 2^32

2^32 is the average amount of hashes in a difficulty 1 share.

So in effect all pools are guessing at hashrates. We have no way to know whats showing up in your client window. In reality it should be called "Share Rate".

Tycho, I propose we change our sites away from "megahashes" and into "shares per minute" XD

That's a pretty arrogant statement!  Smiley

GuildMiners hash rate is also a 15 minute average, updated every minute!

(5x faster than Bitclockers!)

Can't you tack on arbitrary data to a submitted share? Can we like get the popular miners to just tack on a small overhead of rate=X? :]

Would be nice if this became the standard and all pools adopted it.  Technically no pool is accurate when they say XXX MH/s.

To get people use to the idea maybe a combination stat that shows the aproximate hashrate

Something like this:
20.9 shares per minute (~ 1500 MH/s)

(maybe if you mouse over or click on hashrate it would provide an explanation on since no pool can see your hardware hashrate it is estimated based on shares you submit and will fluctuate based on luck).

maybe shares per hour would be better (using a rolling 1hour average?):
1257 shares per hour (~ 1500 MH/s)


I agree, this would be most beneficial to users and pool operators.

Do we have any other Pool operators to give input?
