Are you using the same buffer to glCopyPixels?
On my GeForce4 (*) the following code :

-----------------------------
glDrawBuffer( GL_FRONT);
glReadBuffer( GL_FRONT);
...
glCopyPixels(...);
-----------------------------

is much slower than

-----------------------------
glDrawBuffer( GL_FRONT);
glReadBuffer( GL_BACK);
...
glCopyPixels(...);
-----------------------------
