I bought my first Crucial M4 128gb ssd drive on 03/11/2011
Here is a test just after I bought it:
And here is a test from 13/09/2012
This above ssd was warranty exchanged for a new one.
This is a screenshot from 08/12/2012, after I received new ssd from warranty exchange:
And here is a screenshot from today 09/05/2013:
As you can see in both cases 4k-64thrd is cut in half after a few months time.
It's not like I do something extreme with this drives, I always have updated drivers/firmware, have trim on, never have any viruses etc, my ssd have like 32gb free disk space now.
My most important pc parts are:
16gb ram 1600
Asrock Z77 Extreme6
Asus GTX 670 DIRECT CU II TOP 2GB
CRUCIAL M4 SSD 128GB
2x SAMSUNG 1TB HD103SJ RAID0
And yes ssd feels slower then I remember, windows loads slower. Do I really have to keep sending ssd for warranty exchange every few months now? Not only I lose my main drive for 2 weeks, but I have to rebuild my whole windows installation because of that, I use my pc a lot, and can't afford that to happen. I originally paid like 150 pounds for this drive, and didn't expect this kind of unreliability.

It seems to be normal behaviour I'm afraid after the drive has seen some use: http://forum.crucial.com/t5/Solid-State-Drives-SSD/low-4K-64Thrd-with-AS-SSD/td-p/84448
It won't affect real world performance as you won't see queue depths anywhere close to 64. You'll rarely see them much above 1. Anvils benchmark at a queue depth of 4 is more realistic: http://www.guru3d.com/files_details/anvils_storage_utilities_download.html

Sorry, I'm using normal to mean common rather than expected.
I'm guessing you're a gamer from your system specs? There's a pretty good article on it here: http://www.tomshardware.com/reviews/ssd-gaming-performance,2991.html The vast majority of work occurs with a queue depth of 1.
By all means if you're not happy with the drive then please do contact Crucial support. There just isn't a solution I know of that we can provide you with on here I'm sorry to say.
