[9fans] file server speed

2014-07-15 Thread kokamoto
I've experienced three kinds of Plan9 file servers, Lab's one, 9atom and plan9front. I felt that the file server speed is 9front 9atom lab's. This is based on verious different machines for each. Is my feeling wrong, or hasve some base facts? This is to prepare the fastest file server on a

Hi, What is the simplest storage filesystem in terms of code size in plan9? I’m looking for a very simple in-kernel filesystem. Maybe older version of plan9 was including such a filesystem? On Linux for instance the minixfs was probably the simplest filesystem. The dos must also be simple but

I don't know anything about ramfs but maybe you can modify it to read all disk from storage then write back when done? Sounds really inefficient though. Maybe if it was done with system files it'd be more practical. AFAIK, but a bit off topic, DamnSmallLinux can do this. Maybe you'd like to check

I’m looking for a very simple in-kernel filesystem. What's motivating the desire for to be in-kernel? Nearly, every file system in Plan 9 runs in user space. All the ones that have been mentioned do. The only in-kernel file system in the labs' distribution is devroot which is read-only and

I’m trying to make a tutorial explaining the code of a not too large kernel (9), but there are too many things to explain so I have to cut things. So having a simple fs which does not require to explain 9p, the rpc, the mount device, etc would be great. I know that explaining plan9 without 9p is

not a fair comparsion. Yes, I'd have been more specific. my intension was cwfs fossil+venti of 9atom fossil+venti labs. I did not consider kenfs itself, because I consider it should be file+auth+cpu server. The last is not important, but for drawterm from others. Recent kenfs can be such a
