Hi all ;)
im working on high performance dns server using perl , its nearly completed but
i had some very urgent and bad looking problem ,
well , im using single hash value to store all queries , for example
$mhash{"kernel.org"}{"MX"} returns cached MX query of kernel.org , the problem
is , the data is not cache-able across threads ( threads are making query ).
here is some solution and why i think they are not very usable , please correct
me
1 > using IPC::Shareable
very limited , i ran out of space for locks .
2 > using threads::shared
looks like its unable to share second and third level of my %mhash .
3 > in memory databases using DB_file
just like threads::shared its unable to handle second and third level of my
mhash .
ideal solution would be some kind of "Unlimiteed Ipc::Shareable" module , any
idea please ?
