What do you mean by "download of records" ?
EPESI loading time when opening the application can be long - depending on your network connection speed, server configuration etc. - but still within few seconds. For example our EPESI loads in about 2.5 - 3 sec.
After the application loads any subsequent pages should be much quicker and our goal is to be less than 1 sec. For example opening CRM Companies group takes about 900 ms (0.880 sec to be exact):
If you are getting 25 sec than you have a serious configuration problem (not to mention ~10 min reported earlier). The only time to get such a high loading time would be running some report that collects and calculates a large number of records or importing data. Otherwise it should be rather quick. Is the performance of your installation of EPESI similar to what you get on our demo? http://epe.si/live-demo
