[quote=“qgates”]Check also that the disk holding your project is in good shape, both at the filesystem level (chkdsk, fragmentation etc) and also at the low level (smart errors, sector/seek errors etc.). For the latter you can check the system event log for errors reported by the “disk” service.
If there are disk problems, especially low level, this will cause things to get very slow indeed as your system gets stuck in endless timeout/retry loops that sublime is unaware of.
You can also check that windows hasn’t fallen back to PIO (vs. UDMA) access mode for the project’s drive as well. This creates CPU load and slow everything down like hell.[/quote]
SSD, I have no problem with it whatsoever. I did a benchmark on it just to have done it, and it’s in good shape; no errors in system log.
