Bitcoin Core 0.13 How many addresses it can **effectively** manage? I want to know, what's the maximum amount of addresses that Bitcoin Core 0.13 can manage?
All addresses should belong to the default account. 


I want to use walletnotify feature
How startup time depends from the number of addresses my wallet holds?
How all other JSONRPC calls behave if my wallet holds many addresses?
Try it yourself. In Tools, Debug Console, try getnewaddress. Create as many as you want. See if your wallet performance changes. wallet.dat size will grow, but I can't 4MB vs 32MB has made much of a difference. 

DASH wallet when it generates 1,000 addresses at a time for its PrivateSend feature, I can't notice any difference in performance.

"Effectively" manage is really seeking an opinion where the system components the node is running on will tell you what it can handle "effectively".
