Wait, do you expect you can reduce 100% saving of co_code object? co_code takes 0byte? You said "the overhead it just takes a byte code w/ 16 opcodes before it breaks even" later. So I believe you must understand there is overhead. > I was just measuring the web site code, and not the other various Python > code in the process (e.g. no std lib code, no 3rd party libraries, etc...). > The IG code base is pretty monolithic and starting up the site requires about > half of the code to get imported.

Absolute number is not important here.

"25% of the serialized data" is misleading information. You are trying to reduce memory usage, not serialized data size. You should use ratio of total RAM usage, not serialized data size. > I can't make any promises about open sourcing the import system, but I can > certainly look into that as well. Open sourcing is not necessary. Try it by yourself and share the real number, instead of number of your estimation. How much RSS is used by Python, and how much of it you can reduce by this system, actually?
