Benchmark Madness

Guillem Cantallops Ramis writes: "In Bulma (Balearic Islands LUG) we've done real benchmarks this time: Mongo benchmarks (designed by Hans Reiser and used to test ReiserFS, slightly modified by me to support XFS and JFS), kernel compilation benchmarks, and a small "database simulation" benchmark. You'll find everything in english this time, with benchmark results and interesting comments by Dr. Ricardo Galli (Universitat de les Illes Balears, UIB). Have fun... and switch to a journaled filesystem now!" The previous article was here.

How about directory lookups?

[jandrese]

One advantage that ReiserFS and XFS are supposed to hold over ext2fs and other ufs based filesystems is the directory lookup time on directories with moderate to moderatly large numbers of files (1 million to 10 million or so). Does anybody know of any benchmarks available on the net that can backup this claim? If you want to test it yourself, you can look into Postmark which is easy to compile and simulates a heavily loaded mail or news server.
Unfortunatly the primary site appears to be down (I just downloaded the file a couple of days ago!), but if it comes back the primary distribution site is: http://www.netapp.com/ftp/postmark-1_13.c


Down that path lies madness. On the other hand, the road to hell is paved with melting snowballs.

Re:New Filesystems Aren't Apparently Faster

The only advantage the new FSes hold is probably their journaling capability, leading to faster fscks, faster bootups and less risk of data loss.

Yah, those worthless little things; faster recovery, preserving data and faster boot-ups.

Huh?

Oops, it's not yet in the standard kernel. Oops, the patches don't apply against the latest, most debugged versions of the kernel. Not, it's not time to switch now. I'll stay with stable and standard functions, thanks

Let me check menuconfig on what I got from kernel.org... okay, Linux Kernel v2.4.4 Configuration: File systems ... Quota support ... Kernel automounter support ... Kernel automounter version 4 support (also supports v3) ... Reiserfs support.

It is in the latest stable kernel.

out with the old in with the ....

[da groundhog]

ok, i can kinda see a kernel compile cause of all the io but what ever happened to good old find and grep. Certainly they could have come up with some better tests.

find / |grep blah

SEE, now that's alot of IO

ReiserFS cooler than I thought...

...and a small "database simulation" benchmark.

Wow. Does this mean it can handle SQL Server? That's always been my favourite database simulator.

New Filesystems Aren't Apparently Faster

[absurd_spork]

It's really amazing that all these new filesystems that people have invested tremendous amounts of work into are not really significantly faster than the good old Ext2; ReiserFS is better in some disciplines, admittedly, but in others Ext2 is best.

The only advantage the new FSes hold is probably their journaling capability, leading to faster fscks, faster bootups and less risk of data loss. Did we really need a new set of filesystems for that? ( BSD Soft Updates show that the whole speed and reliability advantage can be had with old filesystems as well!) Where's the advantage? Where's the progress? The benchmarks only leave me disappointed.
