Downloading a zip file, unzipping, analyzing content.
For now I changed it to use a temporary directory on the disk. Later I'll measure if the ramdisk provides a real speedup and then I'll further investigate how to use it.
Comment on Re^2: Sys::Ramdisk as regular user on Linux
Speedup is unlikely. Dirty pages aren't written to disk immediately. Well, if your archives are of considerable size AND your swap is much faster than regular storage, then you'd see benefits.
I'd advise setting up your whole system to use tmpfs backed /tmp instead of mucking around with userspace options (FUSE, etc.) Incidentally, there are FUSE filesystems to access archived content.
