javascript - Poorly Performing Query -

-

i have server using store log files using mongodb. problem while browsing revision have notable delay , performace spike on server. there better way folowing:

function getrevisionslist(project,callback){ mongoclient.connect("mongodb://localhost:27017/devbed", {native_parser:true}, function(err, db) { tmp=[]       if(err) { console.dir(err); }       db.collection(project).find({}).toarray(function(err, items) {         fillrevarr(tmp,items,0,project,callback);       db.close();       });    }); }  function fillrevarr(tmp,items,i,project,callback){     console.log(items)     num=json.stringify(items[i].revision).replace(/["']{1}/gi,"");     tmp.push("<a href=\"/"+project+"/"+num+"/log\">"+num+"</a>")     if(i==items.length-1){callback(tmp)}     else{fillrevarr(tmp,items,(i+1),project,callback)} }

which gives me array of revisions.

do not transform resultset array. use cursor instead:

var cursor = db.collection(project).find({}); cursor.each(function(err, item) {     // ... });
