Filesystem Performance

[taousif]

Hi ,

Can any body tell me what are the parameters to be considered for analyzing the performance of the filesystem.



Thank you.

First thing is that the filesystem is a tool like anything else a computer is for. You need to think of your overall objective (host a fileserver, webserver, mail client) and tailor your filesystem to match it.

In the end, it may be that the differences in filesystems will provide only trivial differences, and that ease of use will be the #1 concern.

We'd need to know more about your specific use to give any kind of advice on filesystem usage.

Thanks for your reply.
I want to know what are the parameters to be considered while evaluating a filesystem's performance. I mean the factors which are to be considered to evaluate performance of FS.

While considering the filesystem performance we have to consider

1. The number of files and directories within each parent directory it will holds (hierarchical directory structure)

2. The larger file size it will hold for a singe file

3. How efficiently it will maintain the file table

4. Query or response time when we requested a file.

Thanks,

Can you please suggest me some references so that I could refer them.

What is your purpose in these questions??

[taousif]

The purpose is that, I want to analyze the performance of the filesystems so which are the parameters to be considered for the same.

[Dapper Dan]

Can't give you the technical reasons why, but I prefer XFS.

[taousif]

I don't want the Filesystem, I just want to know what are the parameters to be considered for performance analysis on any filesystem.

Basically throughput and latency.

But there are a lot of cases to consider.
small/big files, random reads/random writes, linear reads, linear writes.
various caches, filesystems..

I believe Iozone Filesystem Benchmark is quite usefull to get an impression.
