So many questions. The JVM is the same 1.8.0_65. The server is the same and empty (nobody is working on it except me) The network connection is the same (same cable, same client same browser) but different client exhibits a constant behaviour in 7 and a very variable behaviour in 8 (but on the same client is stable). What do you mean with test setup ? I use my application as test. No Apache in front, directly calling Tomcat. Memory tuned ? no tuning at all raw, standard installations for both 7 and 8. Tks Tullio
