Hi. I'd like to attend the event to discuss the following topics: 1. cleancache extension In containerized systems, when containers are more or less equal to each other, we can save RAM and (!) disk IOPS if we share equal files between containers. We've been using a unionfs-like approach and faced several disadvantages of it (I can describe them in details if required). Now we're working on extending the cleancache subsystem to achieve this sharing. The cost of fully isolated filesystems is very high, I can provide numbers of various performance experiments, thus this is required badly for containers. 2. memory checkpoint/restore Yet another project I'm working on is CRIU -- checkpoint-restore in userspace. One of the problems we've met is -- it's impossible to determine a task's current working set from the usepspace. Another problem of the nearest future is the ability to create the memory snapshot of a running task for more efficient migration and incremental checkpoint.
