Dear Yen-Tang Chen,
how many webapps have you deployed on Tomcat? a good test could be to include
in tomcat just the jspui to check the real startup time, check the startup time
for each specific webapp.
My suggestion is to have solr on a separate tomcat, this will allow a more easy
tuning of the system performance and save a lot of time in restarting the
service as SOLR usually doesn't need to be restarted at all (you can hot-reload
the configuration if needed).
Let me know.
Andrea
PS: recently I face with a project where tomcat reside on a NFS... this
situation drastically drop the system performance. In such scenario the
assetstore can stay on the NFS but all the other content (logs, webapps, tmp,
etc.) should move to fast drive

Dear Bollini Andrea
Installation environment
Centos 7 (vmware memory 12 GB)
jdk1.8.0_101
postgresSQL 9.5
tomcat 8.0.37 ('JAVA_OPTS=-Djava.awt.headless=true
-Djava.security.egd=file:/dev/./urandom -Dfile.encoding=UTF-8 -server -Xms512m
-Xmx2048m')
dspace-cris-5.6.1
I follow the method you provided
"add almost all the jars name that are inside the webapps/jspui/WEB-INF/lib
folder at the end of the tomcat.util.scan.StandardJarScanFilter.jarsToSkip
property in the catalina.properties file."
The total time to restart tomcat is 10 minutes that dspace-cris started.
This is my starting time for using the Dspace-CRIS-5.6.1
Always restart tomcat time is 10 minutes.
But I only use Dspace-CRIS-5.5.0 encounter this problem
org.apache.jasper.servlet.TldScanner.scanJars At least one JAR was scanned for
TLDs yet contained no TLDs. Enable debug logging for this logger for a complete
list of JARs that were scanned but no TLDs were found in them. Skipping
unneeded JARs during scanning can improve startup time and JSP compilation time.
After I use Dspace-CRIS-5.6.1 did not encounter this problem!
I don't add almost all the jars name that are inside the
webapps/jspui/WEB-INF/lib folder at the end of the
tomcat.util.scan.StandardJarScanFilter.jarsToSkip property in the
catalina.properties file.
restart tomcat time is 10 minutes.
I add almost all the jars name that are inside the webapps/jspui/WEB-INF/lib

restart tomcat time is same 10 minutes......
