Let's look at the slow queries in the Slow log now.
Once we have fixed them, then lower this to 2:
Current long_query_time = 10.000000 sec.

Also read this for tuning advice. (Some of what they say as OK, is not.)

query_cache_size = 512M -- TOO BIG; 50M, max.

[OK] InnoDB data size / buffer pool: 35.4M/512.0M
-- Not OK; wasting nearly 500MB. Change to
innodb_buffer_pool_size = 40M

[OK] Key buffer size / total MyISAM indexes: 8.0M/59.4M
-- With 12GB of RAM, you may as well have
key_buffer_size = 70M

table_cache = 4096
-- too big (unless you are running a version that hashes the entries)
