Heho, > BTW rpki-client is one of the (relatively few) cases where softdep is likely > to give a significant improvement in performance. I took this as motivation to do some benchmarks (defaults, noatime, softdep, noatime+softdep, mfs, mfs+noatime) on a VM with eight cores and 8gb of memory using a dedicated 10gb disk for /var/cache/rpki-client.
(Preliminary) results here (currently avg. over 7-8 runs, will be 11): https://storage.fiebig.nl/s/84TpQCTrQpa3S9j Bottomline: - Things are a lot faster all of a sudden. This might be related to more cores (8 vs. 2 before) or more memory (8 vs. 4 before), a background task having been running on the disks during the last tests, or the negative impact of those initial boxes having had all files in one partition. I will at least test the last case after the current benchmark has completed. - noatime does not seem to have a major effect, and seems to reduce performance upon import. - You are right; softdep is nearly as good as mfs. With best regards, Tobias
