That said, if swap I/O is genuinely a hard requirement for particular workloads, zswap's per-cgroup writeback disabled mode (see the above incompressible data section) lets you completely prevent disk swap I/O for specific cgroups without giving up zswap's integration with the rest of the memory management subsystem. You can even do some mixing and matching: latency-sensitive services can use zswap with writeback disabled, while other services use the full zswap-then-disk tiering. This is considerably more flexible than the one-size-fits-all zram approach.
Bash: .bashrc is only executed by non-interactive shells; .bash_profile is only executed by interactive shells. To run your setup regardless of shell type, put everything in .bashrc and source .bashrc from .bash_profile.
