How to reduce number of requests dojo makes to the server?

Question

I am using Domino 9.0.1 with Fix Pack 5 which gives me dojo 1.9.7. In my xsp properties I have it set to use runtime optimized JavaScript and CSS resources. I was expecting this setting to greatly reduce the number of requests made to the server when loading an XPage but it only had a minimal effect.

The culprit is dojo.js - it is doing a little over 100 separate requests to the server for various .js and resource files. I assume these are coming from the various controls I am using that utilize dojo. Is there any way to consolidate these dojo requests into a single request?

UPDATE: They are just about all coming from /xsp/.ibmxspres/dojoroot-1.9.7/dijit/ and /xsp/.ibmxspres/dojoroot-1.9.7/dojo/ and also a few from /xsp/.ibmxspres/.extlib/dijit/

UPDATE: My XSP settings:

xsp.ajax.renderwholetree=false
xsp.error.page.default=true
xsp.persistence.mode=fileex
xsp.resources.aggregate=true
xsp.user.timezone=true
xsp.html.doctype=html
xsp.theme.mobile.pagePrefix=m_
xsp.application.forcefullrefresh=true
xsp.library.depends=com.ibm.xsp.extlib.library
xsp.min.version=9.0.1
xsp.theme=vi.theme

UPDATE: I am using a dynamicContent control which is automatically loading a custom control which contains a number of controls that use dojo. This results in the XPages engine generating a bunch of script tags with dojo.require() calls in them. These calls are causing over 100 xhr requests by dojo.js.

Are there many files coming from "nls" directories, e.g. http://myserver/xsp/.ibmxspres/dojoroot-1.9.7/ibm/xsp/widget/layout/nls/xspClientDojo.js? — Brian Gleeson - IBM
@BrianGleeson-IBM They are just about all coming from /xsp/.ibmxspres/dojoroot-1.9.7-u/dijit/ and /xsp/.ibmxspres/dojoroot-1.9.7-u/dojo/ and also a few from /xsp/.ibmxspres/.extlib/dijit/ — jpishko

My solution was to include the dojo.require() calls that the XPages engine was autogenerating in my custom control in my theme using a resources tag:

<resources>
        <dojoModule target="xsp" name="dojo.parser"></dojoModule>
        <dojoModule target="xsp" name="extlib.dijit.DynamicContent"></dojoModule>
        <dojoModule target="xsp" name="dextlib.dojo.helper.IFrameAdjuster"></dojoModule>
        <dojoModule target="xsp" name="dijit.Toolbar"></dojoModule>
        <dojoModule target="xsp" name="dijit.form.Button"></dojoModule>
        <dojoModule target="xsp" name="extlib.dijit.Menu"></dojoModule>
        <dojoModule target="xsp" name="extlib.dijit.Tabs"></dojoModule>
        <dojoModule target="xsp" name="extlib.dijit.TabPane"></dojoModule>
        <dojoModule target="xsp" name="dijit.form.DateTextBox"></dojoModule>
        <dojoModule target="xsp" name="dijit.form.TimeTextBox"></dojoModule>
    </resources>

This results in the dojo js files being aggregated. The number of requests went from 134 to 28 after doing this.
