Not only is the bitcoin price breaking records but the network transaction queue (mempool) has also hit an all-time high on May 5. Around 6 pm EST, the network had about 155,000 unconfirmed transactions with over 85 BTC worth of fees waiting to be settled.

The last time the Bitcoin network’s mempool filled up and broke records was on February 22 with over 100,000 unconfirmed transactions. The record was surpassed on Friday, May 5 as the transaction backlog amassed over 150,000 transactions waiting to be confirmed according to Blockchain.info, Statoshi.info, and Tradeblock statistics.

You can see the live statistics on the number of unconfirmed transactions on the block chain here:

It was going down to below 62,000 last time I check about 5 hours ago.
But it doesn't seem to promising since people are just sending micro transactions compiling to the problem.

Why are you mad at them? If they are willing to pay for the fee then it is their blockchain too. Bitcoin was designed to send any amount across the internet and direct to another user, was it not?

On the record high of unconfirmed transactions, would a 2mb blocksize house all that?

Arguably yes, but the effects that increasing capacity promote are more complex.

It's the psychology of supply and demand at work, in essence. The effects of more people using the network (as a result of 2MB or whatever blocksize increase) will, of course, increase the supply of the economic good known as the Bitcoin transaction.

But there is a positive feedback loop produced by that change, the increase in supply increases use of the network commensurately, people will simply justify using Bitcoin in further ways than they did before; new users are attracted by their increased opportunity to observe Bitcoin being used, existing users send more transactions because it's cheap to send again, and spammers will spam more, for their spammy reasons.

Metaphorically, it's similar to the problems of creating road infrastructure; when a new road is built, people just compare this nice new clean, empty looking road with the congested roads they already use, and some of those people come up with reasons to use the new road, and before you know it, the new road is just as traffic jammed as the old ones it sought to provide relief for.

The real answer is not more roads, as it simply begets more people buying and using more cars. A different transport paradigm is the solution, something that inherently has more capacity than we could possible imagine ways to use, we're looking for the Bitcoin equivalent of air travel or spaceflight, really.

Bitcoin "space travel" doesn't have to just be the design backed by Elon Musk, or the different design that Richard Branson funded. It can be any 2nd layer network on top of Bitcoin, there are already a few designs for 2nd layer Bitcoin transaction networks. But I agree that Lightning is a contender.

Whether it is a spam attack or a regular transaction, Bitcoin should be able to cope with this kind of situation.  Bitcoin scaling really need to  upgrade.  We can  assume the spam attack as the possible transaction in the future, when Bitcoin mainstream adoption is achieved then transaction would be much more than this spam attack.  I hope the two political group that had been ever arguing with the scaling come to a term where they both agree and speed up the process of upgrading Bitcoin capacity to scale. 

That is the answer that I am afraid of. Yes with the word arguably. So it mean that some people can also answer a No and there can be an argument that an 8mb blocksize can also be still be made full.
