To what volumes does it make sense to inflate memcached when working with bitrix?

Question

1C-Bitrix

We have an online store with about 100,000 products, we cache filters.
Is there any maximum-rational amount to which it makes sense to inflate memcached?
10, 20Gb - is it acceptable? (We have our own iron server)

Answer 1

none, it is better not to use Bitrix with memcash, the usual opcash works faster, switching Bitrix to memcash will not give you anything.
Memkesh is needed if you store sessions in a cluster, in fact for this it is in the Bitrix VM.
with 100K products, it makes sense to look not at the cache meme, but at the caching of components,
their quality, the number of sections, their bindings.
IO subsystems to the
quality of the stones themselves, their number does not really affect performance, and this has its own specifics.
Optimization of my.cnf and so on and so forth.
And I would also recommend to abandon the standard output of the directory and write it to d7
In general, there is a whole list of options for what needs to be done first of all, here you need a project survey and not an unfounded memcache, which, in turn, does not really help in performance.
