To avoid guess here is a test case

  | import java.io.Serializable;
  | 
  | import org.jboss.seam.annotations.Name;
  | 
  | @Name("testBean")
  | public class TestBean implements Serializable {
  | 
  | 	public final static int ROWS = 1000;
  | 	public final static int COLS = 10;
  | 	public final static int ITEMS = 100;
  | 	
  | 	private String data[][][] = new String[ROWS][COLS][ITEMS];
  | 	
  | 	public TestBean() {
  | 		for (int i=0; i<ROWS; i++) {
  | 			for (int j=0; j<COLS; j++) {
  | 				for (int k=0; k<ITEMS; k++) {
  | 					data[j][k] = "[" + i + "," + j + "," + k + "]";
  | 				}
  | 			}
  | 		}
  | 	}
  | 
  | 	public String[][][] getData() {
  | 		return data;
  | 	}
  | 
  | 	public void setData(String[][][] data) {
  | 		this.data = data;
  | 	}
  | }
  | 

JSF

  |     <table>
  | 	    <tbody>
  | 	    	<tr>
  | 				<ui:repeat value="#{testBean.data}" var="row" varStatus="index">
  | 					<td>
  | 						<ui:repeat value="#{row}" var="col">
  | 							<select>
  | 								<ui:repeat value="#{col}" var="item">
  | 									<option value="#{item}">#{item}</option>
  | 								</ui:repeat>
  | 							</select>
  | 						</ui:repeat>
  | 					</td>
  | 				</ui:repeat>
  | 			</tr>
  | 	    </tbody>
  | 	</table>
  | 

JSP 

  | <%@page import="com.mydomain.biz.bean.TestBean"%> 
  | <html>
  | <head>
  | </head>
  | <body>
  | <table>
  | <%
  | 	TestBean bean = new TestBean();
  | 	for (int i=0; i<TestBean.ROWS; i++) {
  | %>
  | 	<tr>
  | <%
  | 		for (int j=0; j<TestBean.COLS; j++) {
  | %>
  | 		<td>
  | 			<select>
  | <%
  | 			for (int k=0; k<TestBean.ITEMS; k++) {
  | 				String data = bean.getData()[j][k];
  | %>
  | 				<option value="<%=i%>_<%=j%>_<%=k%>"><%=data%></option>
  | <%
  | 			}
  | %>
  | 			</select>
  | 		</td>
  | <%
  | 		}
  | %>
  | 	</tr>
  | <%
  | 	}
  | %>
  | </table>
  | </body>
  | </html>
  | 

I don't have profiler handy, but I swear it was EL functions which topped the list in it.
