Btw, not sure if it matters, but mysql was build on Ubuntu 17.10 with -DWITH_SSL=bundled then the resulting tarball was used on Centos 7, both x64.

Same (unusual) experience with 8.0.4 built from source on Fedora 27. cmake options were as follows:

cmake . -DCMAKE_BUILD_TYPE=RelWithDebInfo -DBUILD_CONFIG=mysql_release -DFEATURE_SET=community -DWITH_EMBEDDED_SERVER=OFF -DDOWNLOAD_BOOST=1 -DWITH_BOOST=/home/openxs/boost -DCMAKE_INSTALL_PREFIX=/home/openxs/dbs/8.0

The following command then took well more than a minute:

bin/mysqld --no-defaults --port=3306 --socket=/tmp/mysql.sock --basedir=/home/openxs/dbs/8.0 --datadir=/home/openxs/dbs/8.0/data --initialize-insecure

Thank you for the bug report. I tested on Windows 10 Pro on the below hardware taking 19 seconds to create the data stuff, do you consider that slow?. Thanks in advance.

Developer commented it's duplicate of private bug which was closed without to fix 8.0, so verifying this public one.
[30 Jan 7:42] Roel Van de Paar
This was tested on a fairly high end machine, so as mentioned time is very slow.
[30 Jan 9:18] Terje Røsten
Hi Roel,

a change to scripts/mysql_system_tables_data.sql caused mysqld --initialize
to perform lots of implicit commits which in turn gives performance issue
on system with slow storage. Issue is fixed upstream.

For the record, what file system are you using?
If using XFS, switching to ext4 might help (as a workaround to next release is available).
[30 Jan 20:46] Roel Van de Paar
Thanks. This was on ext4 (rw,noatime,nodiratime,discard,data=ordered), SSD I think, high end system.
[30 Jan 20:51] Roel Van de Paar
Confirmed enterprise level SSD.
[13 Feb 15:42] Shane Bester
just pass the parameter --innodb-flush-log-at-trx-commit=0 when 
you run the mysqld --initialize
[13 Feb 15:43] Shane Bester
and sync-binlog=0  or --skip-log-bin .....
