Tesseract在Tomcat上运行缓慢

Question

我编写了一个使用Tesseract进行OCR的servlet。我全部在Tomcat WebServer上运行
如果我通过Eclipse测试运行Tomcat的servlet，一切正常。
如果我通过控制台启动Tomcat，则Tesseract的速度要比我通过Eclipse启动Tomcat慢得多。

怎么可能？有什么解决方案可以提高执行速度吗？

    try 
    {
        String content = "";
        int numeroPagine = Integer.valueOf(request.getParameter("numeroPagine"));
        for (int i = 0; i < numeroPagine; i++) 
        {
            if(request.getParameter("numeroAree" + i) != null)
            {
                int numeroAree = Integer.valueOf(request.getParameter("numeroAree" + i));

                {
