不转码小程序内部分数据无显示，转码后又特别慢。载入空白期3-6秒，有什么办法吗？

if (check_str_exists(jmpurl, [‘chosecat’,‘myhe’])) {wx.miniProgram.navigateTo({url: ‘/pages/index/index?url=’ + encodeURIComponent(jmpurl + _URLEXT)});}

else {wx.miniProgram.redirectTo({url: ‘/pages/index/index?url=’ + encodeURIComponent(jmpurl + _URLEXT)});
