We have SharePoint 2019 on-prem environment. We are facing issue with bad page load speed, observed one issue in event viewer across same issue in all WFE's servers (3).

The issue is: An error occured in the blob cache. The exception message was 'The system cannot find the file specified. (Exception from HRESULT: 0x80070002)'.

SharePoint ULS Log details :

Critical
An error occured in the blob cache. The exception message was 'The system cannot find the file specified.

High
Blob cache FetchItemFromWss() failed with exception The system cannot find the file specified

    Hello @MichaelHan-MSFT ,

    You can use the following suggestions:

    1.Reset the cache(index file)
    Site settings >> Site collection object cache >> check the box for “Force this server to reset its disk based cache”
    It will be regenerate cache(index file) when you accessing this page next time.

    2.Install the latest version of security update for SharePoint Server 2019.
    If clean the cache does not work, it is recommended that you install the latest version of security update for SharePoint Server 2019.

    Microsoft Official Resource:
    Description of the security update for SharePoint Server 2019: October 13, 2020

    Here is a similar case for reference: Error occured with Blob Cache in

    Thanks,

    This is normal, actually. If I recall, it is related to the favicon not being available. The ULS logs should have more information on which file is unavailable.

    Slow page load could be indicative of multiple issues, such as poor overall server performance, be it SharePoint or SQL (network, disk, CPU, memory). Or it could be poor page structure (i.e. adding a bunch of List webparts on a page that make expensive queries).

    If you haven't, also take a look at https://learn.microsoft.com/sharepoint/administration/cache-settings-operations.
