Hi all, I'm currently working with our campus IT to identify the cause(s) of a degradation in performance that we've been seeing. I'm relatively new to our library and to ArchivesSpace generally, but I've been told it's been slowing bit by bit for a few years, and the problem has escalated just in the past few weeks. Neither full re-indexes nor our nightly re-starts seem to help.
I'm aware of this page on tuning <https://archivesspace.github.io/tech-docs/provisioning/tuning.html>, which has been quite helpful in addition to suggestions already posted to this list. We're hopeful that moving to external Solr with our next upgrade will also help (currently on 2.7.1), but are still trying other measures just in case it doesn't. While we look more into general best practices for tuning our hosting environment, I'd also like to check with all of you to see if there are common issues that are more specific to ArchivesSpace that we have overlooked and should focus our attention on. Here are a few of our key settings. Our Java memory variables are below. I get the sense that they are higher than average, is that so? ASPACE_JAVA_XMX="-Xmx16144m" ASPACE_JAVA_XSS="-Xss8m" Indexer settings from config.rb: AppConfig[:indexer_records_per_thread] = 25 AppConfig[:indexer_thread_count] = 7 AppConfig[:indexer_solr_timeout_seconds] = 300 And copied from our innodb settings: innodb_file_per_table innodb_flush_method=O_DIRECT innodb_log_file_size=1G innodb_buffer_pool_size=8G symbolic-links=0 max_allowed_packet=128M open_files_limit=9182 I appreciate any tips on what we ought to be looking for. I know it's hard to give advice from afar when each institution's situation is different, but thought it worth asking in case anything jumped out before we turn to technical support.
