Do you mean it is slow? (sluggish) sorry for my english.

My laptop is by far not so good, Dell 1.8Ghz and 2Gb of Memory, and ioccur is
very reactive even on reasonable large buffer (files of 1.2 to 1.5 Mo).
I use it also on other machine (old Amd64) with no problem of performance.
I also tried it in virtual machine with windowsXP and it work fine also.

What is your OS?
Do you use Emacs in X or on terminal (xterm etc..)?

What key sequences do you see in minibuffer?

I think it is may be not a problem of performance but a problem of key
compatibility with your system.
Actually, backspace is bound to ?\d.

Can you do some test on ioccur.el itself and tell me what you see if for
example you enter:

d e f u n backspace backspace v a r

Also if from scratch buffer, you eval :
and press backspace, what do you see in minibuffer?
You should have 127.

Yes please.

Yes it is, i am curious to see what's wrong here, as i use ioccur every
day in all buffers without any problems.
Thanks for reporting.
