Hi Xuelei,

Thanks for your reply.

I think I now know what you mean.

Here it's a new benchmark:
http://cr.openjdk.java.net/~mbalao/webrevs/8223482/benchmark_sslcontextloading_manual_v0.tar.gz

In this new benchmark we measure the following sequence:

long startTime = System.currentTimeMillis();
ctx = SSLContext.getInstance("TLSv1.2");
long stopTime = System.currentTimeMillis();

The SSLContext class gets initialized per run.

We test both NON_FIPS (SunJCE) and FIPS (SunPKCS11) providers.

Results summary (100 runs per case):

FIPS_with_8223482_webrev01.txt average: 314.33 ms
NON_FIPS_with_8223482_webrev01.txt average: 817.91 ms

FIPS_without_8223482_webrev01.txt average: 358.42 ms
NON_FIPS_without_8223482_webrev01.txt average: 771.34 ms

So, yes, it seems that there is a ~6% startup impact on SunJCE. These
numbers are not accurate though because of using
System.currentTimeMillis to measure, they provide just a rough idea.

Kind regards,
Martin.-
