When the reject rate increases, the total hashrate drops. At first I was thinking it was that people were using --no-submit-stale, but that shouldn't account for that much hashrate loss.
I've talked way too much about difficulty in this thread. It doesn't play a factor.
Hash rate drop - Assume 100 miners connected to pool. They are always connected and always hashing.
- Pool switches to low diff coin (all miners still connected)
- Miners start to get "new block" "new block" "new block" (in my experience this can go on for 10 minutes without submitting a share)
- Hash rate on pool drops (not because miners aren't mining -- they just can't submit shares fast enough prior to a block change)
That's my interpretation of why there is a hash drop. I have 4 7950s connected to your pool, they generally hum along between 2.4mhs - 2.6mhs on a LTC pool. Here, on the pool side by hash rate has been consistently reported as 1.9-2.1mhs. The only thing I can attribute that to from what I see on my end is the "new block new block new block" for 10 minutes without being able to submit a share, therefore to the pool it doesn't look like I'm mining. Just my two cents, I wanted to continue to beat the dead horse. I think share difficulty has everything to do with it, but I'm of a layman viewpoint. Thanks for your hard work and I hope to see this pool get better.

I really think we need two things in this pool. 256 difficulty. 2 payments per day.(i thought we agreed this was ok before?) anyway, since were not constantly mining the same coin, the "512 diff is the same as any other diff" doesnt apply now if we were constantly mining one single coin, that is different. but when we switch to 512k diff coins, and only submit one share in an hour, then it changes to another coin that is 1m diff, then we wasted all that work on nothing.
The diff adjustment I think would help. I have yet to see my hash rate report at or above what I have. It's always about 500kh/s lower. If I was mining solely on an LTC pool I would get credit for those other 500 kh/s. Considering I only have 2,400 kh/s -- that's a lot of credit I'm not getting.

Wanted to provide a bit more information about the problem that I noticed has been going on in this pool lately in the hopes that it can be fixed or explained.
I actually take my mining stats from the pool and record them every few minutes (all day long) to see what is happening in order to evaluate pool performance. In doing this, I get a fairly detailed understanding of the workings and don't get misled by minor trends. My little program factors in all aspects of the mining output (including immature and unexchanged), not just the balance available at the end of the day to transfer out. I generate trend information data every few minutes, and summarize like data together until the trend is broken. I produce summary statistics during every like trend period. As mentioned before, have 2.4 Mhash pointed at the pool.
It generated about $10 a day 3 and 4 days ago (and I was not mining for about an hour each day). That level I defined as good. Then a couple of days ago I noticed that it appeared to start mining some coin with a very low difficulty (the miner just reports a constant string of "new block" messages). While this coin is being mined, statistics go to pot, almost nothing gets posted to the account in any form until the pool switches to another coin. I have had occurrences where my gross balance (including immature and unexchanged) actually go backwards while this type of mining is in progress for 30 minutes or more (some immature coins previously mined get killed, and there is nothing productive to replace it). Typically, you can also see the pool's total reject rate skyrocket (mine as well), moving on multiple occasions to 30% of the total shares submitted by everyone in the pool. It appears that everyone is caught working on obsolete shares or something. Once the pool moves back to a "normal" coin, things go back to normal and the coin mining rate trends back to normal rates (was about .005 bitcoins per hour previously, for last 2 days down to .0025 per hour, which are rates of approx $12 and $6 per day. The pool continues to jump into these coins for various periods, and stats go to pot consistently at these times. At one point, my shares were rejected over 50%. Not sure who is benefiting when these coins are being mined, but it certainly is not me. This has caused my total production to drop from the $10 per day reported earlier down to less than $6 now.
I understand that mining is a random payout and there are multitudes of factors affecting the payout. I have studied this particular effect in enough detail (and it is rather consistent), so I believe that it is not a random effect at this point. I also noticed that the pool had a few hiccups in the last day or so, and I have factored out these time periods.
The premise of this pool is great, and I'm a big fan. Love the idea, and think that if properly implemented the operator(s) could and should make plenty of $$$. However, unless the operator(s) can tackle this problem of autoswitching into dud coins, I'm going to have to mine elsewhere. I'm posting this in the hopes that the operator(s) are not aware and can look into this problem and make adjustments to protect the viability of the pool. Maybe the low difficulty coins are great for some segment of the miners (huge ones?) but certainly not for the 2.4 Mhash crowd like me.
Please advise if there is something that I am wrong about, as I don't want to move elsewhere but cannot ignore the facts...
I'm right there with you and I have the same hash rate as you! So yes, it's a problem -- but it's an inherent problem that I don't believe can be fixed without splitting the pool to low diff coins. The problem with that is -- who gets the profit from the split? Sometimes the lower diff coins are 800% as profitable as BTC. With this the diff is usually less than 1. If you throw 600Mh/s at a low diff coin then you get the results you described.. "new block new block new block reject reject reject accepted" -- obviously some people are getting accepted shares. But, isn't that happening to everyone on the pool equally? Meaning, everyone is still splitting the profit from the low diff coin -- just with less accepted hash rate. I'm not sure why the last few days this pool has paid less than just mining LTC -- but I'm almost to my end. I'll give it another day or two, then I'm with you and on another pool.

Today's payout is 18.4 BTC, with an average hashrate of 728.9. We made 0.0253 BTC per day per MH/s.
What's the problem ? We made a half of normal. If you were mining BTC you would have .0134 and if you were mining LTC you would have 1.2237 LTC or 0.03375 BTC. So mining the most profitable didn't seem to turn out right today. But, there are still a lot of immature/unexchanged coins left from the day..

Did this coin die?
 { "blocks" : 1401, "currentblocksize" : 0, "currentblocktx" : 0, "difficulty" : 1.16415604, "errors" : "", "generate" : false, "genproclimit" : -1, "hashespersec" : 0, "networkhashps" : 9295574, "pooledtx" : 0, "testnet" : false } So.. solo is out of the question, there a private pool somehwere?

I'll sell you feathercoin for twice the price listed on cryptsy.com.
I think I'll pass on that. I would like to buy through the forums because I prefer them to exchanges. Please only post/send logical offers and use common sense. Thank you That is a logical offer. If you are too incompetent to setup an exchange account I'm more than happy to help you, for a premium.
