Hi Masa ,
following your very detailed and helpful instructions we noticed the following
1. all Odata Services response times using /IWFND/GW_CLIENT were good
2. Using Firefox instead of Chrome or IE we had in most cases better performance ( not always acceptable but simnifically better )
3. In Firefox also we get the following message (and picture ) , saying that SAPUI5 is not working for our mobile devices , which is somehow annoying for our users
Any comments or suggestions
Regards
Apostolos
