Can you post the sizes of the returned pages in the thread? I guess this

The pages are roughly similar in size:

Also, consider to move to cocoon 2.1.6, now here is why:
http://issues.apache.org/bugzilla/show_bug.cgi?id=31760
I saw you canged some pools inside tomcat. Did you changed some cocoon
pools? Did you adjusted cocoon memory usage inside cocoon.xconf?
 

Hm - I didn't (until just now) see that there were pool sizes specified 
in the cocoon.xconf. These are the values that I have

 <xml-parser class="org.apache.excalibur.xml.impl.JaxpParser" 
logger="core.xml-parser" pool-grow="4" pool-max="32" pool-min="8">
   <parameter name="validate" value="false"/>
   <parameter name="namespace-prefixes" value="false"/>
   <parameter name="stop-on-warning" value="true"/>
   <parameter name="stop-on-recoverable-error" value="true"/>
   <parameter name="reuse-parsers" value="true"/> <!-- EM: changed-->
   <parameter name="drop-dtd-comments" value="true"/>
 </xml-parser>

 <xml-serializer 
class="org.apache.cocoon.components.sax.XMLByteStreamCompiler" 
logger="core.xml-serializer" pool-grow="4" pool-max="32" pool-min="8"/>
 <xml-deserializer 
class="org.apache.cocoon.components.sax.XMLByteStreamInterpreter" 
logger="core.xml-deserializer" pool-grow="4" pool-max="32" pool-min="8"/>

I removed the store janitor and switched both the store and 
transient-store to Whirly Cache.

 <transient-store logger="core.store.transient">
       <backend>com.whirlycott.cache.impl.ConcurrentHashMapImpl</backend>
       <tuner-sleeptime>10</tuner-sleeptime>
       <!-- evicts least frequently used items when pruning -->
       <policy>com.whirlycott.cache.policy.LFUMaintenancePolicy</policy>
       <maxsize>10000</maxsize>
 </transient-store>
 <store logger="core.store">
   <parameter name="use-cache-directory" value="true"/>
       <backend>com.whirlycott.cache.impl.ConcurrentHashMapImpl</backend>
       <tuner-sleeptime>10</tuner-sleeptime>
       <!-- evicts least frequently used items when pruning -->
       <policy>com.whirlycott.cache.policy.LFUMaintenancePolicy</policy>
       <maxsize>10000</maxsize>
 </store>
