CodeIgniter + Session usage with Redis is slow

[bunglegrind]

maybe this is related:

#6157

From what I understand the CI does its own session lock treatment, correct?

Can I then use PHP's default session_start() instead of using the CI or will that cause a problem?

I only set sessions at login time, otherwise I don't change them.

Correct, the problem is the fixed long interval (1 second). Default interval for the PHPRedis driver is 20 ms...
You have two alternatives:

1. Extend (or edit...) the CI Session redis driver in order to customize the lock polling timeout to a more reasonable smaller value (in case, follow what I wrote in #6157 and substitute sleep with usleep)
2. dealing with sessions outside the framework. That is, use $_SESSION, the phpredis settings in php.ini etc..
