My advice to the OP:
You are not going to improve the operation of Mavericks on the machine that you have now.
Your best option would be to "downgrade" to Mountain Lion. I predict -- no, I'll go beyond that and -guarantee you- -- that ML will run far, FAR better for you than Mavericks does now.
If you're not willing to do this, better get used to the "sluggishness" of Mavericks.
Or, consider getting a new Mac....
