I found a solution for how slow this can be, and here's why - the component runs a search for each keypress, so if you type "t-e-s-t" really fast, that's still 4 searches!

1. Replace on line 28(ish) of mod_rsfinder.php
document.getElementById('rsquick').onkeyup = generateResults;
with
document.getElementById('rsquick').onkeyup = timerGenerateResults;

2. If you add this just before generateResults(e) on line 107 of mod_rsfinder.js


var generateResultsTimer = 0;
var timerGenerateResults = function(evt){
if(generateResultsTimer > 0){
console.log("Cancelled timer " + generateResultsTimer);
clearTimeout(generateResultsTimer);
}
var callback = function(){
generateResults(evt);
}
generateResultsTimer = setTimeout(callback, 1000);
}

This will make sure that keypresses that are less than 1 second in between will not cause multiple searches blocking the XMLHttpRequest thread count of 2 (which brought my searches from 12s to 3)

Thank you for the code snippet, we have added it to the RSFinder! package.
