Performance downgrade from version 1.1.3 to 2.0.0

[murilohns]

Consider this code:

  const decryptedJWE = await jose.JWE.createDecrypt(keystore)
    .decrypt(encrypted_data)

  const jwtPayload = decryptedJWE.payload.toString()

  const jwsPayload = await jose.JWS.createVerify(keystore)
    .verify(jwtPayload, { allowEmbeddedKey: true })

  const stringifiedWebhook = jwsPayload.payload.toString()

  const webhookResult = JSON.parse(stringifiedWebhook)

I had a lambda function using the libray 2.0.0 version. And when I execute this code, the time to finish it process was 12 seconds.

Then, when I downgrade the library version to 1.1.3, the time to process it take 5 seconds or less.

Lambda configuration:
Node version: 14
Memory Size: 128 MB

Tip: upgrading the memory to 1024MB decrypt the content 10 times faster.
