Has anyone else noticed significantly worse performance when reading from a MySQL table over the past couple days?
Today we are seeing errors across multiple apps that worked perfectly last week. Each app is experiencing a severely slowed sync time when reading from a large MySQL table. The table is large but reasonably efficient and we did not have this issue previously. It started either today or over the weekend.
I’ve traced the problem down to the lowest level in the performance monitor and it does not appear to be from virtual columns or anything else except simply reading from the table.
