For the past 24 hours RVN / x16R mining was a disaster ! http://zerg.zergpool.com/site/mining All my miners were receiving stratum errors with "server is full" or connection denied and the server was not able to allow more than 1000 RVN miners without errors to a part of the miners.
1)
Do you know if load balancing was implemented for x16r ?
you should have 2 or 3 stratum instances for x16r and use round-robin to balance miners
there should be the public port for RNV that is from load balancer
and the load balancer distributes the the miners to all stratum instances with port1, port2, port3
also ZPOOL and many other pools have load balancing for stratum servers implemented to allow more than 1000 miners per stratum instance and per coin and have instances respond really fast to sudden new connections requests
2)
don't you think that having very low difficulty allowed on many algos creates a lot of problems on your server ?
if you check the stratum source-code you will see that every accepted share automatically has an "insert into database" query
if I am allowed set the difficulty low, I spam your server with 10 shares per second from each miner and each share means an INSERT query into your MYSQL database that is not very fast because each index for columns must be created after each insert, and that is creating a LOCK on that table for each insert. Why do you think NiceHash and so many other pools have high minimum difficulty ??
It should be fixed, don't you think ?
