Hi, Scenario: We have millions of little (almost all < 10 kB), about 30 GB total. It takes > 24 hours to either tar them up or then untar them.=20 It finally occured to us to put them into a file-backed memory disk. Questions: 1. How does the performance of a file-backed memory disk change as it becomes large? 2. Is there a clever way to make such a file-backed memory disk bigger after the fact? If I want to expand my 30 GB file to 50 GB, am I stuck with just making a new one and copying it over? TIA!
