There is a good thread on memory use on GlassFish at the USERS alias. In the use-case described, the main issue was JSP compilation. Memory consumption is much lower (and compilation is also much faster) in GlassFish v2 using JDK 6 because JSP compilation is done in-memory, using JSR-199 and without forking. Forking can also be avoided in GF v1 and in earlier JDKs with some caveats. Check the mail thread for details. |
Picture is a close up on Core Memory. Ah... the good? old days of core and Punched Cards! Have you ever dropped your deck of cards and had to reorder them? That is what those extra columns in the punched card were for :-)...
