Hello,
> this should improve the situation, even if I still observe some > inconsistent execution duration. I tried to use the two following pragma: --8<---------------cut here---------------start------------->8--- PRAGMA synchronous = OFF PRAGMA mmap_size = 10737418240 --8<---------------cut here---------------end--------------->8--- hoping that mmaping the Cuirass database and disabling synchronisation would help, but there were still inconsistent duration. I have now copied the database to a tmpfs mounted directory to make sure that those inconsistent duration are only caused by the I/O pressure on berlin. Thanks, Mathieu
