I have seen this doc:
http://search.cpan.org/~bsugars/IPC-Shareable-0.60/lib/IPC/Shareable.pm
I'm interested in using the IPC::Shareable module.Does this method suit for my
situation?Because there are so many socket requests coming into my socket
program on everytime,when each request coming,I fork a child process to handle
it.And,where in child process,I tie and lock the global variable %hash and do
motification to it.Since the actions of 'fork' and 'tie' happen so
frequently,is there any performance drawback to the program?thanks again.
