Swapfile
Warning: Never put the swapfile on a brtfs partition.
Instead of creating a large swap partition, you can create a Swap file, which will be dynamically enlarged and reduced based on need.
If you have a /var partition, it would probably be best to put the swapfile under /var.

Swappiness
You will want to reduce your system swappiness to as low as possible.

Profile-sync-daemon
Relocate your Firefox/Chromium profile to your RAM, to reduce read/writes on the SSD.

To enhance performance, you can also make overlayfs mode available to psd by allowing your user to run the psd-overlay helper tool.

tmpfs for compilation
Compile your programs in the tmpfs, to reduce wear on the SSD.
You can set makepkg to use the built-in tmpfs by setting /etc/makepkg.conf's BUILDDIR to /tmp/makepkg.
Note that if the file you are compiling is in the range of hundreds of megabytes, you may want to compile on the SSD instead by prefixing such a command with BUILDDIR=. .
BFQ Scheduler
Consider using the Linux-ck kernel, which contains the Brain Fuck Scheduler (BFS) and Budget Fair Queueing (BFQ), offering significant speed improvements for SSDs.
