Populating listbox with Font Families is slowing down my form

In my form load I have code that populates a dropdownmenuitem with font families.  It slows down my form loading just a tad.  Is there a way to speed that up?
//POPULATE FONT NAMES
            FontFamily[] ffArray = FontFamily.Families;
            foreach (FontFamily ff in ffArray)
            {
                if (ff.IsStyleAvailable(FontStyle.Regular))
                {
                    toolStripDropDownButton1.DropDownItems.Add(ff.Name);
                 }

eager load it in a static List<FontFamily> at form load time like this:-

private static List<FontFamily> lstFonts;
public void Form_Load(object sender, EventArgs args)
{
lstFonts=LoadFonts();
}

private IList<FontFamily> LoadFonts()
{
return FontFamily.Families.Where(f=>f.IsStyleAvailable(FontStyle.Regular)).ToList();
}

Try this:-

        private void Form1_Load(object sender, EventArgs e)
        {
            var fonts = LoadFonts();
            fonts.ForEach(f => toolStripDropDownButton1.DropDownItems.Add(f.Name));
        }

        private static List<FontFamily> LoadFonts()
        {
            return FontFamily.Families.Where(f => f.IsStyleAvailable(FontStyle.Regular)).ToList();
        }
