Number of bytes in 1 I/O call

[gerjam]

Hi HP experts,

I need to know the range (upper and lower limit) regarding the number of bytes read in one I/O call. What commands do I need to issue? Thank you.

Rgds,

Read the Manpage of iostat.

That will give you information of your current I/O traffic. One I/O Call to a Filesystem depends of the Blocksize. You can get the blocksize of your FS with fsytp.

Since HP-UX 11.11 you can tune I/O Parameters for a FS. Read vxtunefs and tunefstab manpage for this.

What kind of I/O ? (Disk, Memory, other device)

What hardware?

What OS & Release are you running?

What kind of devices?

Glance will give you much of what you seek.
