conntrack has two distinct table size settings: nf_conntrack_max and nf_conntrack_buckets. The former limits how many conntrack objects are allowed to exist in each namespace. The second sets the size of the hashtable. As all entries are inserted twice (once for original direction, once for reply), there should be at least twice as many buckets in the table than the maximum number of conntrack objects that can exist at the same time. Change the default multiplier to 1 and increase the chosen bucket sizes. This results in the same nf_conntrack_max settings as before but reduces the average bucket list length.

README
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
