Macbook lagging, becoming hard to use

I am running a late 2009, 13-inch Macbook with a 2.26 GHz Intel Core 2 Duo Processor. I am running Yosemite OS X 10.10.1 with 4GB of Memory. I have a 250 GB hard drive, with 36.88 GB free. Over the past few months, I've noticed that my computer lags really badly with just about everything. Opening up applications takes forever, and then once they are open, they freeze up constantly. For example, opening safari windows often leads to freezing (spinning beach ball) and slow loading pages. But it's not just Safari...it happens with mail, iTunes, etc. I've run the basic Onyx Maintenance tasks every so often, but it doesn't seem to make much of a difference in performance.

I tried doing a clean install of Yosemite and only put my essential apps and files back on to computer. Unfortunately, no improvements. Any tips on what I can do to speed things up and reduce the lag and constant freezing? I can provide any additional information that would help.

Thanks!

OS X Mavericks (10.9.4)

Replace the hard drive.

Since you've already done a clean install - and I am assuming you had the same issue prior to filling the drive back up to 85% full. Your hard drive is dying. If you don't have a backup - you need to backup "NOW".

I agree with Tom that it is LIKELY to be the hard drive starting to fail. You could try upping the RAM (which I'd suggest anyway -- that model can do 8GB I believe), and you could try erasing the drive with a single pass of zero's (this would lock off bad sectors), but given the cheapness of replacement drives, why bother. Replace it (you'll need a #00 phillips screwdriver and a #6 torx, per instructions on ifixit.com).

Hello chas_m fancy meeting you here discussing 'memory'. :)
I have been looking around at RAM and now would like an opinion on which is the best of the bunch. I have come across - Crucial, Western Digital, Seagate, Toshiba, Hyper Kingston to just name a few. If you know of a better one please tell me.
At present my MBP is using 2 x 4GB, DDR3, 1333 MHz. Early 2011 - 2.3GHz i5 inte core.
I believe it will take up to 16GB.

Yes I think it will take 16GB. Crucial is well-thought of around here, it's what I used for my 16GB upgrade.

There are many variants to their specifications. The one's Crucial recommend on their web page for my MBP would they be the only one's I could use ( in those spec's ).
What I mean is there are SO-DIMMs can I use these also, or just stick to what they suggest.
When you start looking ( and not having a lot of knowledge ) it does become confusing, so I'm just after some help in choosing which ones I can use.
Thanks for your patience.

Way... way too many specs to list.
Stick to their suggestions, you do need DDR3, 1333 MHz.. else it's likely the machine will not boot.

I would suggest you do not have enough storage spare. Although 10% - 15% is often enough 20% is better. You have 36.88 Gb free, 50 Gb would be better. Reduce your storage, usually media is easiest eg movies. Don't forget to empty trash.
Use Disk utility to Erase Free Space and assuming you have a complete backup run Repair Permissions.
See how it runs after that.
If you still have the same problems use Disk Utility to Verify HD.
