Re: [dspace-tech] New installation of DSpace 5.5 with migrated data rendering pages after ~40 seconds

Wow, that's great, Andrea. I'm very curious to try your patches. I will play with them and see if I can get them to apply to our slightly modified DSpace 5.1 code base. Cheers, On Fri, Aug 12, 2016 at 8:53 PM, Andrea Bollini wrote: > Dear Alan, > > on DSpace-CRIS we

Re: [dspace-tech] New installation of DSpace 5.5 with migrated data rendering pages after ~40 seconds

Dear Alan, on DSpace-CRIS we have make the indexing process multi-thread and for our experience this improve the performance a lot, 10x or more depending on the number of threads used and the server configuration. See

Evelthon, Interesting observation about the indexing speed. Just yesterday I posted a message about Java JVM settings for Solr/Lucene to this mailing list. I'm sure there is room for improvements in Solr performance if you're willing to monitor, tweak, monitor, tweak, etc. I've stayed away from

Re: [dspace-tech] New installation of DSpace 5.5 with migrated data rendering pages after ~40 seconds

I'm glad you solved it, Evelthon. I guess it depends on your OS and how you have Tomcat running. In Ubuntu we set JAVA_OPTS in /etc/default/tomcat7, but CentOS's Tomcat is surely different. By the way, there's more discussion about tuning DSpace (including JAVA_OPTS and CATALINA_OPTS) on the

Re: [dspace-tech] New installation of DSpace 5.5 with migrated data rendering pages after ~40 seconds

Hello Luigi, CATALINA_OPTS did it. All works good now. Seems like solr was choaking and caused slow loading on the UI. Curious though, shouldn't it fallback to java_opts? In any case, thank you. Evelthon On Thursday, August 11, 2016 at 1:01:34 PM UTC+3, Luigi Andrea Pascarelli wrote: > >

The server has 32GB, postgresql on different box. I don't think it's a RAM issue. I am wondering if it is a solr issue. I don't have tomcat running as user dspace. Instead, I change ownership in [dspace]/solr to dspace:tomcat and gave rw rights to both user and group. Thanks On Thursday,

Re: [dspace-tech] New installation of DSpace 5.5 with migrated data rendering pages after ~40 seconds

Hi, >From your JAVA_OPTS I see you are allocating 4096 + 2048 megabytes of RAM to Tomcat right from the start. How much memory does your server have? This means your host must have AT LEAST 6GB of RAM just for Tomcat, let alone PostgreSQL, Solr, and the rest of the operating system. I wouldn't be

[dspace-tech] New installation of DSpace 5.5 with migrated data rendering pages after ~40 seconds

Hello, I seem to be having an issue with tomcat. It takes ~38+ seconds to load pages. I believe it's tomcat since i notice shell scripts ( [dspace]/bin/dspace ) executing slow when tomcat is started, and very fast (normal I presume) when tomcat is stopped. The system is a new
