If that's not motivation to make it load fast, I don't know what is什么意思?what is 没这句型吧,有没有省略

If that's not motivation to make it load fast, I don't know what is
什么意思?what is 没这句型吧,有没有省略

整个句子应为：if that is not the motivation to make it load fast,i don't know what is (the motivation to make it load fast).这样看就清晰了.

如果不是激励让它迅速加载的话，我就不知道是什么（让他迅速加载）了。
这里的what is应该少了个it吧，应该是what it is，这是宾语从句。
