Performance Considerations
Server speed, server disk speed and network speed can constrain the overall performance of a cifs
mount, but in some cases, client client configuration settings can be changed to increase performance:
1) size of file write (wsize). The Linux CIFS client usually sends 56K writes (14 pages) and is
limited to 56K maximum unless mounted forcedirectio.
2) size of file read (rsize). The Linux CIFS client usually sends 16K reads (4 pages). Since CIFS
large network buffers are about 16K in size by default, increasing the rsize would have little
effect unless the setting of module load parameter CIFSMaxBufSize (via insmod) also is
increased.

I just lower the block of data what i want to write.

you can use command “modinfo cifs” to get the cifs read or write buffer size and buffersize scope.

At 8PM I found similar errors and SAR showed %system cpu at to 99% and staying there until the server had was rebooted 2 hours later. I am guessing this post might have saved my ass..

I love to get them making a beep when they have completed the boot process, and now I'm adding a beep to know they have acknowledge when I manually push the power down button. But I wanted to do it with style, so I'm searching for nice beep tunes. Yours is splendid!!! I'm going to search in your blog if you have posted more tunes. Now, I'm trying to find short tunes, like the power rangers clock, or the star trek communicator. If I make my list, I'll let you know!
