The "only" config you can change for this pool is intensity and even then its not possible (e.g. 280x).

People pointing at your config, where totally underestimating how overloaded the (only) server was.

Some people had already good configs and after trying elsewhere got good performance and only when they were here they had high rejects. Higher than the expected 10%~ due to the coins that are mined...

Whats a bad config? What setting on the miner did you change? You know that queue, scan time and expiry have no affect and its all driven by the server.

In my subtle way and thanks to Kalroth, it was proved that really the only setting available to you is intensity.

Actually to clarify, Kalroth verified that cgminer code deferred to server derived settings for expiry, queue and scantime when those values are available versus what is set in your config/bat files.

What gets buried in this thread is his statement that he doesn't know whether Clevermining's servers provide these settings as part of the stratum handshake.

In truth, most Altcoin pools do NOT pass these settings down to the client. So these settings can actually still be set on the clientside and have some effect since there are no server settings provided by the pool to default to.

Kalroth - feel free to chime in here to help clarify your statements further.

If you don't specify them the client uses the default setting, which if set by the server is used. After test I found using various settings including these didn't really help. Once I changed to the Asia server, performance improved. Proof is in the pudding, the US server at the time was overloaded it had nothing to do with a "bad config".

I was being reasonable to, I was willing to put up with no more than 10% rejects.

That's actually reversed... the way the code is written is that the server settings takes precedence. This was the point that Kalroth was making.

But that only holds true if the settings are actually delivered by the server, which in the case of this pool and quite a few others (I dare say most Altcoin pools), they are not. At that point it's either your custom settings or the defaults builtin to CGMiner/SGMiner.

Just because they had minimal effect in your particular setup doesn't mean they won't work for someone else, especially when the server is not setting your q, e, s for you.

I can't say for sure if they work on here, but I was getting fairly high rejects, usually higher than average, before I added q, s, e. After I added them, my rejected shares went down considerably to 2.4%. Now on US East server I am at 0.3% rejected shares after 24 hours with those settings. The average on that server seems to be 2-3%. This is just my observation on my own rigs; it may or may not be coincidence.

I am using queue 5 scan-time 1 expiry 1. I picked these because these are the suggested settings on the Middlecoin wiki.
