AES256加解密非常慢？有知道怎么解决的吗？

[dte2mdj]

do {
let aes = try AES(key: key, blockMode: CBC(iv: iv), padding: .pkcs7)
var decryptor = try aes.makeDecryptor()

} catch {
print(error)
}

Same Data in different Build Configuration md5 encode have different time, in debug just using 0.5 sec, but in release need 20 sec! confuse -.-?

Looks like block main thread, i even switch async thread, but can't slove.
then i using CommonCrypto to translate, it's working so fast in any Configuration.
