Bug ID: 53492
Assignee: dev@tomcat.apache.org
Summary: Make JspC shell multithreaded
Severity: enhancement
Classification: Unclassified
OS: Mac OS X 10.4
Reporter: d...@fabulich.com
Hardware: PC
Status: NEW
Version: trunk
Component: Jasper
Product: Tomcat 7

patch
Jasper works great multi-threaded. Using two threads per core substantially
improves throughput on my test machine, reducing the time it takes to build
from 9 minutes to 2 minutes.
The attached patch adds a new -threadCount command-line argument to JspC, as
well as a setThreadCount setter, suitable for use in an Ant task. It accepts a
positive integer, or a core factor like "2.0C" which means two threads per
core. 2.0C is the default.
Note that on my machine it didn't help that much unless JspC was also
configured to -compile the classes.
I've attached a patch.
