Well, now that I seem to have Coda-4.6.1 working on PPC, I was considering seting up my two machines as servers and starting to place some data on them. (I want to have two machines with replicated volumes for data redundancy, plus having a coherent filesystem which doesn't depend on either machine being up all the time, as NFS would) I re-initialized RVM with a 30 MB log and a 90 MB data partition, and a ~ 1.8 GB /vicepa, and created a coda:root partition. I then ran bonnie, and got the following results: -------Sequential Output-------- ---Sequential Input-- --Random-- -Per Char- --Block--- -Rewrite-- -Per Char- --Block--- --Seeks--- MB K/sec %CPU K/sec %CPU K/sec %CPU K/sec %CPU K/sec %CPU /sec %CPU 10 77 1.8 90 0.9 85 1.6 95 1.5 96 0.4 37.0 1.7 What's going on here? Is this because I'm running the client on the same machine as the server? Is there some strange deadlock going on? I'm using a 2.1.115 vger cvs kernel (vger is a cvs archive with the most recent PPC changes) and the coda-linux-2.6.2 venus client, and my patched coda-4.6.1 server. What kind of performance do you get with the in-house Coda servers at CMU? (and what kind of machines are they?) I also ran this from an old slow 486/33 client running 2.0.35, and to my surprise, the results were better: -------Sequential Output-------- ---Sequential Input-- --Random-- -Per Char- --Block--- -Rewrite-- -Per Char- --Block--- --Seeks--- MB K/sec %CPU K/sec %CPU K/sec %CPU K/sec %CPU K/sec %CPU /sec %CPU 2 208 29.1 246 12.9 139 13.7 203 36.1 279 18.1 61.5 18.6 -------------------------------------------------------------------------- | Troy Benjegerdes | troybenj_at_iastate.edu | hozer_at_drgw.net | | Unix is user friendly...
