after i upgraded to the  bitcoind latest version 0.12.0, the i set paytxfee = 0.0001 on the bitcoin.conf  as like previous version.
and restart bitcoind.

but the transaction fee was very low as  0.00005xxx.

how can i set the paytxfee  on the version 0.12.0 as like previous version.???

Its per kbyte.

ok , if paytxfee is set 0.0001 and  transaction is  smaller than kbyte , the transaction fee must be  0.0001 .
so i think minimum transaction fee  must be 0.0001 btc. 

but it is not on the version 0.12.0
.

AFAIK this isnt new in 0.12. If you set 10k satoshi per kbyte and your TX is 250 byte it will pay 2.5k satoshi as fee.

Thanks ,then if i want to set minimum fee to become 0.0001btc, how can i set ????.  
Because i think fee have to  be more 0.0001 to be confirmed quikly.

It depends on the size and network load. If there is no solution to this (none that I can think of, maybe shorena may have one), the best solution is to use floating fees[1] with a -maxtxfee=[fees in total].

Id go with estimatefee[1] just keep in mind that it can return -1 which means it has not enough data so you need to catch that if you are issuing payments automatically. If you are using the GUI it will not let you slide to 1.
