Slow performance - optimization request


Recommended Posts

Hello, ever since converting to ipb from vbulletin our forum is suffering very slow speeds.

Here is the output from mysqltuner

    MySQL was started within the last 24 hours - recommendations may be inaccurate
    Reduce your overall MySQL memory footprint for system stability
    Dedicate this server to your database for highest performance.
    Configure your accounts with ip or subnets only, then update your configuration with skip-name-resolve=1
    Increasing the query_cache size over 128M may reduce performance
    We will suggest raising the 'join_buffer_size' until JOINs not using indexes are found.
             See https://dev.mysql.com/doc/internals/en/join-buffer-size.html
             (specially the conclusions at the bottom of the page).
    When making adjustments, make tmp_table_size/max_heap_table_size equal
    Reduce your SELECT DISTINCT queries which have no LIMIT clause
    Before changing innodb_log_file_size and/or innodb_log_files_in_group read this: https://bit.ly/2TcGgtU
Variables to adjust:
  *** MySQL's maximum memory usage is dangerously high ***
  *** Add RAM before increasing MySQL buffer variables ***
    query_cache_size (=0)
    query_cache_type (=0)
    query_cache_size (> 128M) [see warning above]
    sort_buffer_size (> 756K)
    read_rnd_buffer_size (> 1M)
    join_buffer_size (> 656.0K, or always use indexes with JOINs)
    tmp_table_size (> 74M)
    max_heap_table_size (> 74M)
    innodb_log_file_size should be (=1G) if possible, so InnoDB total log files size equals to 25% of buffer pool size.

Hey there!

Are you just looking for suggestions, or are you interested in hiring one of us to perform a detailed tuning of your server and IPS configuration for you?

If it's the latter, I'd be happy to offer my services to you. Server tuning usually runs around $300-$600 depending on the amount of work needed, how thorough you want the service to be and the size of the community.

If you're interested, just send me a message here!

1) Convert MyISAM tables to InnoDB

2) Make sure that your MySQL server is tuned for InnoDB.

3) Follow the general recommendations

Beyond that, you haven't really clarified - are you sure MySQL is the problem? There are many web server optimizations that can make a huge difference too. Do you use a CDN of any sort, or reverse proxy caching?

Thank you very much.

I am not sure mysql is the problem, simply making sure the configuration is optimized to eliminate mysql as a suspect.

Do you think it might be the apache, php configuration? anything specific I should l check for optimal IPB performance?

I don't use CDN or proxy caching. There is however, Redis installed and configured with IPB.

Optimizing a server is a huge task and it's hard to give a lot of general "do this" recommendations. Most suggestions are specific to an environment.

For starters, I'd make sure that (1) you don't have things installed and running that you don't need. The less PHP modules, Apache/nginx modules and so on that are executing, the better off you'll be. And (2) make sure your configurations for Apache/nginx, PHP and MySQL are as optimal as can be. There are thousands of tutorials online that can help you determine what the optimal configuration for your environment and level of traffic should be, and I'd start with reviewing some of those. Basic things like ensuring static files are cached can go a long ways.
