Now I have deployed my MyEclipse webapps to the ISP I have run into out of memory problems. So I have got them to give me more memory – its now running at 128m heap with 128m permgen as well.
But that is costing me more, and as importantly, I realise I need best possible response times.
I have 2 web apps running – one supports the other via Restful requests. Both are MyEclipse Sping scaffolded on.
Now I want to add more but am worried that will require more memory.
Questions:
– does 128m heap with 128m permgen sound reasonable?
– having multiple web apps – does that mean I an holding the same classes in permgen multiple times? If so, how can I hold just one?
– what tools are there for measuring / optimising response times?
– where can I learn more about memory optimisation?
