We have recently updated HTMLUnit from 2.15 to 2.23 after which we are
facing memory and cpu utilization issues. Below is the code snippet for open
and close connections for webclient. Please review and provide some
feedback:

openSession(){
                        WebClient _webClient = new
WebClient(BrowserVersionFactory.getBrowserVersion(browserVersion));
            _webClient.getOptions().setSSLClientCertificate(url.toURL(), new
String(selfSignedCertificate), "JKS");
            _webClient.getOptions().setUseInsecureSSL(true);
            _webClient.getOptions().setTimeout(Config.getTwbTimeout() * 1000);
            _webClient.getOptions().setCssEnabled(false);
            _webClient.getCookieManager().setCookiesEnabled(true);
            _cookieManager = _webClient.getCookieManager();
            _cookieManager.setCookiesEnabled(true);
            _webClient.getOptions().setJavaScriptEnabled(true);
            _webClient.getOptions().setRedirectEnabled(true);
            _webClient.getOptions().setThrowExceptionOnScriptError(false);
            _webClient.getOptions().setThrowExceptionOnFailingStatusCode(false);
            _webClient.setAjaxController(new NicelyResynchronizingAjaxController());
}


closeSession(){
              try{
            if(_webClient != null){
                List<WebWindow> windows = _webClient.getWebWindows();
                for (WebWindow wd : windows) {
                    wd.getJobManager().removeAllJobs();
                }
                _webClient.getCookieManager().clearCookies();
                _webClient.close();
            }
        }catch (Exception e) {
            TPLog.writeLogMessage(Log.WARN, ERROR_LOG+command+e.getMessage(), e);
        }
}
