    Function Compute:What do I do if "could not determine the L2 cache size on this system, assuming 256k" is reported?

    Last Updated:Apr 08, 2024

    Error analysis

    The following message in function logs indicates that the L2 cache size of the system cannot be determined and the default value is assumed to be 256 KB. 

    could not determine the L2 cache size on this system, assuming 256k

    Possible causes

    Some dependent libraries attempt to automatically detect the L2 cache size of the system in order to optimize performance. Runtime environments of Function Compute are strongly isolated sandbox environments. The L2 cache size cannot be specified. Even it is configured, the specified L2 cache size does not take effect.

    Solution

    Ignore the message because it does not affect normal running of functions.
