I'm only getting 13 kh/s using minerd with intel i5 and the lowfeemining.org pool. Shouldn't I be getting a better hashrate?
Assuming that IsraCoin uses the Scrypt-Hashing algorithm as suggested in the comments on the question, I found this hardware overview table on Litecoin (which also uses Scrypt).
The table lists a number of
Intel Core i5 processors ranging in hashrate from 12 to 55 kHash/s.
I.e. depending on what processor you have exactly and whether IsraCoin uses the same hashing scheme as LiteCoin, it is within the expected performance.
