Ez Find Update Index Clean taking too much server resources

Wednesday 13 January 2010 4:43:26 pm - 4 replies

Hi all,

I'm having problem to make a clean indexing of my production site. The updatesearchindexsolr.php --clean script takes too much resuorces of the server. I check the server processes and it seems that java and mysql are draining all memory and processor and as this is my production machine the web server serves the pages really slow. I tried to put a "nice" linux command to see if the process drains less resources but as the script calls mysql and java that have unlimited use of resources as they are used in the web server, is there a way of limiting the resources usage so I can run a clean indexing?

Thank you all for your time and take care

Hi Julian,

re-indexing indeed needs a lot of cpu/disk resources, mainly on the ez publish side (pulling data and assembling the ezp objects)

You could insert usleep() or sleep() in the update script, but then re-indexing may take too long

Hi Paul,

Out of curiosity, would it help to tune Java as explained on ?

And what about updating a staging area with production files and database, running the re-index on staging, and then move the solr index file over to production?

Thanks Robin

Hi Robin

Tuning helps yes, and also using a staging index helps (you can simply copy over the index files). For more intensive sites with lots of search traffic, a master slave config for Solr may be an even better alternative.

But again, even when re-indexing with a tuned eZ Find/Solr, its still the eZ Publish side that is slow

@Paul, thanks for elaborating on this.

@Julian, hopefully this shows you some directions in improving the performance of re-indexing your site.
