URL: https://github.com/apache/incubator-tvm/issues/6356


   Dear developers,
   
   I was optimizing a TextCNN model with TVM on intel x86.
   I wrote my own Conv1D NCWc schedule based on Conv2D

   TVM stack only has operator-level performance tools. 
   **How could I further locate the hot-spot of the operator**  ?
   
   I tried gdb, and the ZMM registers was utilized.

   I also tried linux-perf, but didn't get much clue.
   
   
   I asked the same question on [TVM 
discuss](https://discuss.tvm.ai/t/how-to-further-improve-the-performance-of-given-schedule/7711),
 but got no reply.
   
   Sincerely hope for your reply.
