I'm not sure of the speed, but F5 load balancers run a custom version of TCL to process requests. [1]
Been that way for a long time, so I imagine it has been pretty optimized over the decades.

- interroboink 4y agoI would be extremely surprised if they don't still support traditional iRules syntax (or even offer Lua, honestly).

There is a gargantuan amount of legacy code and support to consider.
