I’m currently supporting about 100 users in a PL class using the handin server and writing their programs in Typed Racket. This load is really wrecking my VPS. I upgraded to a larger VPS, and I’m still getting many users timing out. The problem is that although this is an 8-core machine, racket is just running the handin server on just one of them.
Has anyone looked into using places to allow handin to be distributed? I suppose the alternative would be to run four or eight standalone server processes and use proxying at the HTTP level to connect to the servers. I don’t really know which would be better/less work. Also, because I just thought of it: would it make any sense to shift the burden to the user’s computer by designing the handin server to accept a compiled .zo file? Or is it more difficult to sandbox a compiled .zo file than source text? Any opinions appreciated Many thanks, John -- You received this message because you are subscribed to the Google Groups "Racket Users" group.
