Sorry if this has already been asked.
Who is responsible for fast pool switching? The proxy or the rig?
If I rent a rig running a custom cgminer/sgminer/bfgminer/whatever that has been configured/patched for - say - 30 seconds pool switch. Will this rig switch pools faster than a rig running standard cgminer 3.7.2 with 300 seconds pool switch?
Yes, it will be based on the settings in your miner. I use Kalroths cgminer v3.7.3 and i think he set the default there as check every 60 seconds, worked flawlessly this morning for my first customer.
