The default keypool is set to 1000. What does it mean exactly? That I have a pool of 1000 keys/address to use?
If you have a HD wallet (check the icon on the bottom-right corner in Bitcoin Core), it doesn't matter.
Thanks for a clear answer. just to make it sure, if my wallet(s) are HD (which I do by default) I should not mind about keypool size and I can use 10 of 20 for that matter?
Also I made a mistake:
and loads much faster?
Should have been a fact, not a question.
When I tried to load/create 100 wallets (in multi-wallet mode), they were loaded/created in no time. as opposed when using the default 1000 keypool.
