MFE cache

Open the MFE cache

In the Dalfin sidebar, select Settings, then MFE Cache. The page opens: "Warm, refresh, and evict the registry's editor graph caches." While it loads you see "Loading cache status...".

Read the figures

The tiles at the top show how many MFEs are Resident (loaded in memory) and Cold (not loaded), the LRU cap (the most that can be loaded at once) and the Idle TTL (how long an unused MFE stays loaded). Process memory shows RSS, Heap used, Heap total and External memory.

Keep the page up to date

Auto-refresh is on by default and updates the page every 5 seconds. Untick it to pause, or select Refresh at the top of the page to reload the list now. This page-level Refresh only re-reads the cache status; it doesn't change any MFE.

Check the resident MFEs

Under Resident, each row shows the MFE with its share of memory, and its Files, Nodes, Watcher and Last used time. The largest are listed first.

Warm a cold MFE

Under Cold, select Warm next to an MFE to load it into memory.

Refresh a resident MFE

Select Refresh on a row to drop that MFE and rebuild it from disk straight away. This is not the same as the Refresh button at the top of the page, which only reloads the list.

Evict one MFE

Select Evict on a row. In Evict MFE?, select Evict. The MFE is removed from memory and rebuilt from disk the next time it is used.

Evict all MFEs

Select Evict all at the top. In Evict all resident MFEs?, select Evict all.
