well I hadn't got a clue about this vm stuff but I read that
there are CALL, GOTO and SWITCH [vm?] models implemented. according to
'Seb' CALL goes fastest. But I would assume that offering different vm
models meant that raw speed is not the only factor (otherwise why not
concentrate all efforts on just the CALL code) - could someone** give a
hint (or a link :-) as to what the VMs mean for people who have the choice?
(i.e. in full control of the server running their code)
I could imagine that the different VMs are tuned to different styles of
code (e.g. OO & procedural) or different tasks? (web, cmdline, deamon)
....is this anyway near the truth?
rgds,
