I updated http://pkeus.de/~wb/mventi, adding a file mventi.c which is venti.c + parts of index.c (to avoid linking the real index.o).
I have some performance data now. I had to add a 4th arenapartition, which sealed the old partitions, so readonly acces is sufficient for them,. I served the partitions on the original venti system via nfs. On my AMD A10 workstation (32MB, 4 cores) it took 12min real time to vcat a 50GB ffs partiition to /dev/null. On the WD Mycloud system ( on which the arena partitions are local, ithe same task took 33min. mventi: > time vcat ffs:ef6c183eabb7caafed7f85a3447a12accfbbeb8b > /dev/null > 1540096 blocks total > 1214607 blocks in use, 2754705 file reads > > real 12m11,573s > user 2m33,463s > sys 0m34,604s original venti: > ime vcat ffs:ef6c183eabb7caafed7f85a3447a12accfbbeb8b > /dev/null > 1540096 blocks total > 1214607 blocks in use, 2754705 file reads > 504.283u 94.546s 2000.095r vcat > ffs:ef6c183eabb7caafed7f85a3447a12accfbbeb8b > I should add the remark, that I was quite content with the performance of the same file served as a dump file system ------------------------------------------ 9fans: 9fans Permalink: https://9fans.topicbox.com/groups/9fans/T21878aa53884911b-M019008e416672a06797b66a8 Delivery options: https://9fans.topicbox.com/groups/9fans/subscription
