How do I quickly export a layer as a png file in Photoshop with extendscript

Question

I need to export every layer as png file, just like the context menu item(Quick Export as PNG) of layer does. Currently, I do this by:

... // Hide all layers
layer.visible = true; // Show the current layer only
doc.trim(TrimType.TRANSPARENT)
var options = new ExportOptionsSaveForWeb()
options.format = SaveDocumentType.PNG
options.PNG8 = false
var saveFile = new File(destFileName);
doc.exportDocument(saveFile, ExportType.SAVEFORWEB, options)

It does work, but it takes about 2 seconds for a layer in several PSD files. Why is it so slow? Is there a better approach to do this? like using runMenuItem()?

// export activeDocumentquick_export_png(activeDocument.path.fsName)// export activeLayerquick_export_png(activeDocument.path.fsName, true);function quick_export_png(path, layer) { try { if (layer == undefined) layer = false;  var d = new ActionDescriptor(); var r = new ActionReference(); r.putEnumerated(stringIDToTypeID("layer"), stringIDToTypeID("ordinal"), stringIDToTypeID("targetEnum")); d.putReference(stringIDToTypeID("null"), r); d.putString(stringIDToTypeID("fileType"), "png"); d.putInteger(stringIDToTypeID("quality"), 32); d.putInteger(stringIDToTypeID("metadata"), 0); d.putString(stringIDToTypeID("destFolder"), path); d.putBoolean(stringIDToTypeID("sRGB"), true); d.putBoolean(stringIDToTypeID("openWindow"), false); executeAction(stringIDToTypeID(layer?"exportSelectionAsFileTypePressed":"exportDocumentAsFileTypePressed"), d, DialogModes.NO); } catch (e) { throw(e); } }
