It's the SecureRandom initialization.  You could just force such an
initialization at startup so that startup has a bit of a slowdown, but then
it runs fast the rest of the time.

Subject: cryptography - slow starting????


I have successfully built a servlet that uses JCE to encrypt data and
deployed it under JBoss Tomcat 2.4.1-3.2.2.

The very first access is VERY slow as the cryptography classes do some sort
of initialisation. I don't know what.

Subsequent actions seem very quick.

Is this to be expected? Can I speed it up? Can I get this initialisation to
take place at start-up before a user accesses the servlet?
