[Glass] Gemstone configurations

[Trussardi Dario Romano via Glass]

Ciao,

FWIW, if you find that you need to have more resources than available with the limited license[1], you can request an unlimited keyfile with a limited duration for experimentation purposes.

	I setup a PC with :

		Core i5	-  8Gb Ram - SSD 128Gb 

		In the next week i will do some experiment to understand the performance of my application based on Seaside.

		My goal is to support 20 - 30 current device on Local Network and relative wifi ( 802.11b or 802.11n)  

		Questions:

			a) In the past i use the Ubuntu 16.04 LTS O/S	It is a best choice?
				
				In future i think to setup a small Dell server.

			b) For the web server i have some experience with Lighttpd http server, 

				but often i found reference to: NGINX HTTP server.
				Considerations?

			c) How many gems i need ? 	One gem for any device ?

			d) How many space a gem required ?  Is configurable?

			e) How many FastCGI run - configured ?

			f) How i can request  a limited key file to do experimentation test ?

			g) I know two parameter for configure the GLASS:
			
				The:  	SHR_PAGE_CACHE_SIZE_KB =  2097152
					
						GEM_TEMPOBJ_CACHE_SIZE = 50000

				There are other important parameters?

				Where i can read about these?

		Thank for any considerations,

			Dario
