I can confirm that you probably have no idea what you are talking about, I run MOON as one of my pools and have no issues whatsoever....
Having run a mooncoin pool myself and a ton of other coin daemons currently that aren't causing any issue like mooncoin, I can confirm that you can gfy
Insulting others won't help the fact that you obviously lack the proper knowledge to run any kind of pool.....

Maybe he's talking about the other coins with little to nothing of hashing power, that don't have a real impact on a weak server.
This is running mooncoin on a personal computer (i7 with 12gb of RAM), not on a pool server. I'm running about 20 coin daemons (litecoin, all merge mine coins, dogecoin, digitalcoin, megacoin, etc etc) and the only one causing any problems is mooncoin.
I had it running as a P2Pool-server on the smallest Pentium available at the moment (G3220) with 4 GB RAM, running besides Vertcoin-P2Pool and Doge-P2Pool on a personal network. And guess what: NO problems whatsoever. The same unproblematic behaviour now on a P2Pool-node at a provider.
So I guess it was a misconfiguration, a bad network-connection, too narrow bandwidth to handle many client-requests at the same time, too much latency in the line to your server (bad router-config or something like that), or a mixture of all the reasons. Or just simply FUD against MOON, as said by Spekske.
