High VLF Count
The SQL Server transaction log is made up of multiple Virtual Log Files (VLF), each addressing a portion of the allocated log space. If the log file grows, the number of VLFs will grow too. However, having too many VLFs can negatively impact all performance that uses the transaction log, even including backing up the transaction log itself.
Reconfigure the transaction log files using the procedures explained in the Resolution section of this article.
Any suggestion from Aireforge should be thoroughly tested before being implemented into production.
