It's hard for me to tell when you wake up, but in reality the number of transactions has been on the rise after Asset Exchange launch, check out the chart:

As you can see, june 7 - 3592 txs per day, that's about 4.5 txs per block or ~150 txs per hour, assuming the NXT network generates on average ~800 blocks per day.

Most blocks are not empty in the past 2 weeks, also proof of the Asset Exchange picking up steam:

Soon the Digital Goods Store and Alias trading will launch, and the number of transactions will increase more.

So please check your numbers again, they don't match with reality
