Hi Racketer I'm trying to load a log file which size is 600MB, then I found the program exhausted 3 GB resident memory just for load all the content of it via (port->lines...). I do have enough RAM but it looks like some thing went wrong here, and I do need to load them all into RAM for my use case so (read-line ...) doesn't help me.
Any comment would be preciated. Here is may programe: #!/usr/bin/racket #lang racket ; Load input as list of lines (define (input-load-lines file-name) (if (file-exists? file-name) (let* ([input (open-input-file file-name)] [lines (port->lines input)]) (close-input-port input) lines) empty)) ; Racket 7.8, compile from source code, (none cs mode) ; 100M of log requires 0.5G runtime memory ; 300M of log requires 1.5G runtime memory ; 600M of log requires 3.0G runtime memory ; ; Reference ; racket/collects/racket/port.rkt :106 ; racket/collects/racket/private/portlines.rkt :11 (define input (input-load-lines "main.log")) ; 214M(VIRT)/101M(RSS) without open any file (let loop() (sleep 5) ; Waiting here so that I can check it via top/ps (set! input empty) ; event not help with this line (loop)) Thanks Hong -- You received this message because you are subscribed to the Google Groups "Racket Users" group.
