solomining -scrypt is very slow (6k hash/s !!!) why?

[toboboto]

how come when I'm running -scrypt (FTC2, worldcoin) coin wallet, solo mining, the solo miner only runs at 6030 hashes per second. I have 5850 and 7850 cards.
set at 12 thread and 99 scantime whatever that means. edit: worldcoin set at default 99thread and 99 scantime and mines 6231 hash / second)

It isn"t slow, just missed the right momment...it's better to mine in p2pool now - http://pool.titanix.net:9999/static/index.html

i don't know i have solo mined for 20 hr and get nothing

is 6231 hash mining in a wallet client normal for a scrypt coin mining on a rig with 5850 and a 7850?
