Me too but I'm trying to improve.
practice makes perfect... just reading an article here and there will improve word recognition and therefore make one a faster reader. Right now when you read english you practically just need to see what the word begins with and ends with and know what it is. In farsi same thing will occur after a certain time. You see the word and you recognize it immediately.
Right now, i actually need to read farsi letter by letter, rather than recognizing the word immediately.
