After upgrade Jira isvery slow and sometimes doesn't respond.

[espeake@dmp.com]

Running on Ubuntu. Update from 7.4.3 to 8. mysql upgraded from 5.5 to 5.7 using 8.0 db connector. Upgraded ubuntu from 14.04 to 16.04.

Since the upgrade it took a ton of time to get things to work. Now they are very slow and sometimes unresponsive. 

error stating that the collate is wrong and that utf8_bin is not supported.  This is from the database:

mysql> SELECT @@character_set_database, @@collation_database;
+--------------------------+----------------------+
| @@character_set_database | @@collation_database |
+--------------------------+----------------------+
| utf8mb4 | utf8mb4_bin |
+--------------------------+----------------------+

Looking for ideas to see what may be wrong

Thank you,

Eric

This was an issue in the setenv.sh file. It was to a minimum. Increased the min-max amounts of memory used.
