I recently installed Arch Linux (with new install media) and on a new SSD (Crucial M4) seems to be sluggish suddenly (UI hangs for 1s and stuff). I read and followed some of the recommendations for Optimization on Arch Wiki, not sure if I did so correctly and perhaps I made a mistake somewhere. Below are some information that might help

I haven't set up swap space does it matter? Free seems to tell me I have enough free RAM?
Oh I also noticed either noatime and/or data=writeback on / (linux partition) seems to cause Arch to boot in read only mode?
What other information might you need? Or what should I do?
I also changed the cache pressure to 50 and swappiness to 1
I notice windows takes about 5-6 sec (fresh install) to boot from after POST into Desktop. But Arch takes slighly more ~10s to get to LXDM login screen (did have packages installed already). This is unexpected!
