I said before cache engines can be faster in both write and read operations. Cache tables are small and not heavily used. You may want to keep some bins in the database, but you should test the memcached backend for most bins. Available cache backends are: We coudl also talk about the lock API in Drupal lock.

Let’s look at a complete configuration, for Drupal6 the cache backport module would require these lines: If you have several Apache servers you will have one APC cache per server, but it’s not a big one, be careful and part of the available memory space is occupied by the opcode. The first question is « where should I put each separate cache bin or each cache table for short? You may want to keep some bins in the database, but you should test the memcached backend for most bins. Use the right tool for the right thing. In case of full cache overflow the cache is completely wiped out, so do not use that for long persistency.

Soon enough you will ask yourself « Could I use some smarter solutions like Memcache for the cache storage? You could drupxl try the filecache backend, with a modern linux kernel often used files will get mapped into memory buffers and you may get good results. You may wonder why it is smart to use something which is not the database to perform the caching storage?

And the answer is that a relational database provides more services, it can for example provide a better persitency, or manage better simultaneous writes, or allow handling relationship between objects. Cache tables are small and not heavily used.

But this is still a good question. More on this module when released like how to manage session locks, how to configure the cache backend for sessions, etc. We’ve just been removing write and read requests from MySQL. But other backends could be written.

But The use of a new Module called Session Proxy should be the definitive solution, allowing usage of a cache backend or druupal of PHP native sessions which can be set to memcache.

The default situation Take your Drupal Database and check what are the cache tables used, here I’ll use a quite basic default Drupal installation on Drupal6: Available cache backends are: This is always almost provided in the module documentation but we will use the cache backport module documentation as an example.

You could maybe avoid completely the database requests in aggressive mode Dedicated storage engine cache engines perform faster than a relational database both in write and read operations Reducing the number of requests made on MySQL is 7.6 important with Drupal, where a single page can be between 50 and requests.

Take your Drupal Database and check what are the cache tables used, here I’ll use a quite basic default Drupal installation on Drupal And now for Drupal7 or Drupal6 we would have of course it depends of the bins available on your installation, check the table ddrupal in MySQL to see what bin are requested by the modules:.

There is no magic rules, the best tool will depend on your cache usage and on used modules. The memcache module, for example. Keep in mind that you should never make a server swap.

So drual a replacement for Cache Router where you can reuse the cache parts of Drupal7 cache backends in a Drupal6 website. But you will need to allow some memory for these new backends, maybe some of the memory given previously to MySQl or Apache. So by definition it’s quite hard to perform some fine tunning on the MySQL server if this table is not removed. But this is not always true, depends a lot on your Drupal cache usages I said before cache engines can be faster in both write and read operations.

And for each bin you can specify which storage backend will be used. Nos formations Formation Drupal Theming.

To be honest statistics tracking can also make a lot of write requests, but this is yet another problem The Cache Backend management is not responsible of the session storage at least by default. In case of full cache overflow the cache is completely wiped out, so do not use that for long persistency.
