node.js - Nodejs (socket.io) memory usage compared to JavaScript's primitive data type memory usage -

-

first off, title may poorly defined or misleading, pretty tries summarize question whole.

i've searched lot without getting questions answered.

  1. how socket.io memory allocation through memorystorage (socket.get/socket.set) work , how memory usage approximately 1 socket.set use? memory freed correctly when socket disconnects? optional: there known memory leaks should aware of in v0.11.0-pre?

  2. how javascript's garbagecollector work objects , associative arrays declared in global scope? memory freed when "delete" key-value pair this: "delete object[key];"? or ram continuely increase client requests increase?

  3. how option 1 , 2 compared each other? should use socket.set on globally declared "maps" when comes increasing , freeing memory? optional: how compared each other when comes performance ("executing" socket.get/object[key])?

as basic information on project, i'm developing game server in node.js (single process) expected accept many clients single server can handle (before extending cluster of servers). optional: there else regarding project should aware of when comes load , memory??

thank time, appreciated!

i've plotted data points , fitted exponential curve between them using 'fit' in matlab. problem fit-function got fitted line wanted plot, markers on top of regular markers. solved problem plotting wanted markers on top of unwanted couldn't seen. problem. when want show legends dots in there. how can remove markers legend without removing fitted line since both of them hidden inside fit-function? can stop 'fit' plotting unwanted markers? so, want remove blue dot called 'hoff' in picture below. you can leave out legend-entries manually leaving out handles of lines, dont want in legend. try this: %if plot something, want showing in legend, save handle: h_line = plot(x,y) %you dont want show line? dont anything, plot it: plot(mymarker) %then set legend-> can add text legend-entries %a cell-array containing strings want show up: legend([h_line another_line],{'text1' 'text2'}) with example (see comments) came solution:

here code using: string string = "08/07/2013".replace('/', '-'); date date = new simpledateformat("yyyy-mm-dd").parse(string); why date return: "wen jan 3 00:00:00 est 14"? not @ date format told use. edit: need format because database using requires format. the format use parse date string, not match it. using yyyy 08 . use following format: new simpledateformat("dd-mm-yyyy") and why @ replacing / - ? can build pattern original string only: string string = "08/07/2013" date date = new simpledateformat("dd/mm/yyyy").parse(string); and if want date string in yyyy-mm-dd format, can format date using dateformat#format(date) method: string formatteddate = new simpledateformat("yyyy-mm-dd").format(date); see also: change date format in java string simpledateformat java doc
