我们有一个运行Apache Tomcat 8.0.41的Solaris SPARC系统（Oracle Solaris 11.3 SPARC）。在这个系统上，我们在小型Web服务器负载下观察到非常高的CPU消耗。具体来说，运行10-15个并发HTTPS请求线程会导致此64 vCPU计算机上的CPU消耗达到80-90％。
但是，当我们通过将SunPKCS11提供程序移动到列表底部来更改java.security文件中的安全提供程序顺序时，在相同的方案中CPU消耗会显着降低（低于5％）。
我们在较旧的Solaris 10 SPARC系统（Oracle Solaris 10 1/13 SPARC）上运行了类似的测试，即使java.security设置和sunpkcs11-solaris.cfg文件相同，我们也没有看到此问题在两个系统上。正在使用的Java版本也是相同的（1.8.0_131）。
我的问题： 1. 11.3版本的Solaris SPARC w.r.t是否存在任何已知问题。 SunPKCS11安全提供商？ 2.除了更改java.security文件中的安全提供程序顺序之外，是否有解决此问题的方法/解决方案？
以下是使用-Djava.security.debug = sunpkcs11选项输出的一些日志：
