I would like to ask everyone about the details of importing FilterFreebase into Virtuoso.

[theBlueDrug]

he size of my FilterFreebase file is 124.05GB. I moved it to the database folder in Virtuoso for import, but I have been unable to import it successfully. The virtuoso.db file is often 66MB in size, and the largest it has ever been is 5GB. Could you please give some advice and guidance? Is the size of my FilterFreebase file itself incorrect?

The settings in virtuoso.ini (which adjust the usage of memory) severely impacts the speed of loading a KB into virtuoso (i.e, creating a virtuoso.db file). You may try to edit the configurations in virtuoso.ini:

;; When running with large data sets, one should configure the Virtuoso
;; process to use between 2/3 to 3/5 of free system memory and to stripe
;; storage on all available disks.
;;
;; Uncomment next two lines if there is 2 GB system memory free
;NumberOfBuffers = 170000
;MaxDirtyBuffers = 130000
;; Uncomment next two lines if there is 4 GB system memory free
;NumberOfBuffers = 340000
; MaxDirtyBuffers = 250000
;; Uncomment next two lines if there is 8 GB system memory free
;NumberOfBuffers = 680000
;MaxDirtyBuffers = 500000
;; Uncomment next two lines if there is 16 GB system memory free
;NumberOfBuffers = 1360000
;MaxDirtyBuffers = 1000000
;; Uncomment next two lines if there is 32 GB system memory free
;NumberOfBuffers = 2720000
;MaxDirtyBuffers = 2000000
;; Uncomment next two lines if there is 48 GB system memory free
;NumberOfBuffers = 4000000
;MaxDirtyBuffers = 3000000
;; Uncomment next two lines if there is 64 GB system memory free
;; NumberOfBuffers = 5450000
;;MaxDirtyBuffers = 4000000

NOTE THAT:
;; Note the default settings will take very little memory
;; but will not result in very good performance

; NumberOfBuffers = 10000
; MaxDirtyBuffers = 6000
