Roundcube webmail slow loading

Dear all,

I am experiencing a severe performance issue with Roundcube webmail v1.6.16 on a specific cPanel account. When users log in, the inbox folder (and occasionally other folders) takes anywhere from 2 to 4 minutes to load.

The cPanel account has plenty of room to breathe, so I don't believe it's a standard resource starvation issue. Here are the CloudLinux LVE limits and current usage details for this account:

  • CPU: 2 Cores
  • RAM: 4 GB
  • Entry Processes (EP): 70
  • Number of Processes (NPROC): 200
  • I/O Usage: 20 Mb/s
  • IOPS: 2024
  • Disk Space: 150 GB allocated (currently at ~50% usage)

Email Account Limits: All accounts are set to Unlimited storage.

Any help or direction on which logs to tail would be greatly appreciated!

Best regards
