Is sgx_aes_ctr reentrant?

$

In my enclave.cpp code, there is sgx_aes_ctr function call.

When I executes my program, it works well but the execution time is not proportional to the number of threads.

I tested with 7700k cpu and 1, 2, 4 threads.

Without sgx_aes_ctr, execution results are proportional to 4, 2, 1 times well.

I am using sgx sdk 1.8 and I realize that the fuction is lapping ippsAESEncryptCTR.
