Your log looks clean to me. However, I noted that there is no firewall running on your system, and that is not recommended.
Here are some recommendations: (please use one and only one. Using more than one is not recommended as it will hog your system resources.) Zonealarm Kerio Comodo
To address your performance issues, may I suggest that you read this thread here on how to speed up your system.
Regards,
Your friendly momok =)
