How to run scheduled script execution on ui action

[Anna_Servicenow]

I have the below UI action-client(scoped) and script include(scoped), When I test with high load, the script is getting transaction cancelled with "maximum execution time exceeded". How can I get this script executed so that its not timed out. Is it possible to run a run scheduled script on click of ui action and how? Please help with script.
script include:

var AttachmentParserScoped = Class.create();

AttachmentParserScoped.prototype = Object.extendsObject(global.AbstractAjaxProcessor, {

    getExcelInfo: function() {

        var currentSysId = this.getParameter('sysparm_sys_id');

        getdata.query();

        if (getdata.next()) {

@Ankur Bawiskar Is it possible to make this script include call asynchronous? 

[Ankur Bawiskar]

@Anna_Servicenow 

try this

function showDetails() {
g_form.setVisible('import_state', true);
g_form.setValue('import_state', 'In progress');
   
    alert("Please wait import is in progress" );

    var systemId = g_form.getUniqueValue();
    var ga = new GlideAjax('AttachmentParserScoped');
    ga.addParam('sysparm_name', 'getExcelInfo');
    ga.addParam('sysparm_sys_id', systemId);
    ga.getXMLAnswer();
}
g_form.setVisible('import_state', false);
