About /etc/fstab, there are mount option which say how the FS are tuned (tmplog,nolog delaylog etc...)
You have here some optimization that could be done but for that we would need to know the type/caracteristics of the disk-subsystem (like hardware RAID5 /cache centric...) or you may generate other issues...
So until you find out this we will put aside...
SWAP
A system will see his performance drop if it needs to swap (your case...) and is using disk swap space..
creating more swap of same size on other devices will balance I/O load...
The system buffers its read/write, oracle also, and worst maybe your subsystem also...
That means that before a modification, or read is done oracle will look in its buffer, then the system, at at last the sub-system, now I have noticed that better can be enemy of good, e.g. to much buffer in oracle will slow the system because of time parsing, compared to go and get the data...
If you know your subsystem has cache then reduce the amount of system buffers
Kernel params:
bufpages 0
dbc_max_pct 8
dbc_min_pct 5
swapmem_on 0
I cant find your values of maxusers... how many concurrent users?
I there a good reason for maxuprc 3686? (like: We all connect using oracle account...) It a heck alot for one user and can cost you as much if you fall on bad written code (infinite loops etc...) on big systems here with OA running (and because of java ) we set it at 1000 then I monitor to see if more is really needed and in most cases, not...
I would reduce of 200000 your redo and data buffers
Can you give this a try and lets see what happens?
(and look what you have in /etc/fstab, and what disks you are attached to...)
Good luck
