Mining Btc addresses with Vanitygen very slow to store them with the o- command

[timeshareafrica]

I would like to find out if there is a possibility to store all new bitcoin addresses which are generated in the RAM ?.

I know the bitcoin addresses can be stored in a txt. file with the -o results.txt command, unfortunately this is way to slow, this will store not all new generated bitcoin addresses in the folder, only a few of them so it is even quicker to use bitaddress.com to generate bitcoin addresses.

If there is a way to store huge ammounts of BTC-addresses with vanitygen in a file, folder or memory other than the -o command let me know. Thanks for a reply.
