Ceilometer Performance

Hi all, We had installed Havana/Mysql as backend and we notice that for querying ceilometer a simple meter-list could take a lot of time (around 30s for ~40 meters), looking at the conf file we found out an experimental feature use_tpool=true that improved the response significantly, now we upgraded to Icehouse/Mongo and the performance issue returned, is there a way to improve the response of ceilometer? e.g when trying to enter just a single data point the response takes 20 sec.

Thanks.
