I recently upgraded from Dragonfish to Electric Eel. From an external perspective, everything is functioning as expected (Apps, VMs, shares, etc.).
However, the internal web UI is now extremely slow to load when accessing existing pools and disks. This is also true for UI forms when a pool is one of the parameters, such as attempting to edit a scrub schedule. This makes working within the interface rather cumbersome.
Server:
Dell R740xd
2x Intel Xeon Platinum 8168 @ 2.7GHz
384GB ECC RAM
SFP+ 10Gbps x4 daughter board
1x Dell HBA330 12Gbps (front bays)
3x LSI 9208-e 6Gbps (external disk arrays)
1x LSI 9208-e 6Gbps (VM pass-though for LTO-8)
Attached devices:
2x VNX6GSDAE25 25-bay 2.5" (single-path)
4x KTN-STL3 15-bay 3.5" (single-path)
1x Dell PowerVault CSEH-001 LTO-8
You can see in the following video, it takes roughly 16 seconds (or 8-10 swipe animations) for the Storage tab to load. Same for the Storage widget on the dashboard, and so on.
Just hoping someone can help point me in the right direction. Thanks.
