I've developed a website in which I want to display posts from RSS feeds from other websites. I've used wordpress ofc and after lots of trial and error with RSS importers I found that Multi-Importer plugin does exactly what I need (no, autoblogged doesn't fit my needs).

My problem is that right now I'm importing feeds from 130 RSS feeds, and the server runs out of memory and website is lagging like hell. I moved the website into a new VPS with 4 cores and 8GB of RAM, and each time it checks for new RSS it takes up all the RAM and every 6 hours it crashes the mySQL server.

So simply put right now the website is very very slow, and every 4-6 hours mySQL is crashed. How to improve the performance of this website?

  • Show us the code you are using so we can see what can be improved, if something. Note that support for third party plugins are off-topic.

Problem solved by changing to InnoDB as storage engine for mySQL and using the following settings:


tmp-table-size = 128M max-heap-table-size = 128M query-cache-type = 1 query-cache-size = 128M max-connections = 500 thread-cache-size = 35 open-files-limit = 65535 table-definition-cache = 4096 table-open-cache = 4096


innodb-flush-method = O_DIRECT innodb-log-files-in-group = 2 innodb-log-file-size = 32M innodb-flush-log-at-trx-commit = 1 innodb-file-per-table = 1 innodb_file_per_table = 1

innodb_buffer_pool_size = 4G
