If you use php as the default serializer in the configuration, then everything works very quickly. But I read that igbinary_serialize works several times faster? But when I turn on serializer igbinary, in the config, I get a critical error in wordpress.

If I use the default serializer (php), everything works well. The download speed of sites is very pleasing. But if you enable serializer igbinary ('serializer' = > 'igbinary',) - Wordpress's fatal error.
I read that igbinary is much faster than php and you can increase the speed of sites.
I tried to deactivate all the wordpress plugins - it didn't help. Changing the various Redis parameters in wp-config also did not help.
