Subject [jira] Updated: (HARMONY-5277) [startup][performance]
Date Mon, 10 Dec 2007 07:45:43 GMT

]

Naumova Natalya  updated HARMONY-5277:
--------------------------------------

    Attachment: jarmapping.BCP.patch

1. Bootstrap jar files mapping : we can deliver from a big amount of system calls (such as
lseek, read etc) by mapping jars into memory via CreateFileMapping for windows  and nmap for
linux. Then we can work using pointer arithmetic only.
