Apache httpd and Tomcat do not share any memory, so there is not any explicit memory-copying going on. If the two processes are on the same machine, and are using the "localhost" NIC, then UNIX is usually smart enough to do memory copies instead of doing all the TCP/IP stuff necessary to send the data to a remote host. > If this is the case... does anyone know if there are plans to use the > new "splice()" method introduced by the new linux kernel to avoid > memory copies? I'm guessing that this isn't going to go into mod_jk at all. But, I'd bet that the kernel loopback TCP/IP driver will make use of this capability. Mladen or Rainer can certainly shed more light on this subject. - -chris -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.7 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iD8DBQFHDlz59CaO5/Lv0PARAi5cAJ9Y30WkaZxu6KtiyeQ3hKqy3+iLIQCfWR7+ 1T8pHDCHnaUvjWIW4szl9E4= =W7UT -----END PGP SIGNATURE----- --------------------------------------------------------------------- To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
