"This", for me, is extremely sluggish notebook behavior in creating cells, and to a lesser extent autocompletion. I'm not sure if its related to the "100% CPU" issue of Kiran.
The first version I saw this in was 3.4, and its still there in 3.4.2. But it seems much much worse on one of my servers than the others - all of which are now running 3.4.2 on the same machine. I just set up a seperate server for a small class and it seems fine, which makes me wonder if the age of my sluggish server is the problem - there are hundreds of worksheets from a variety of users on it. This is on an intel mac pro running OS 10.4. Its very frustrating to my grad students; they sometimes have to wait 10-20 seconds for a new cell to be created after clicking. Its almost impossible to resist clicking multiple times when that happens, and then they get multiple new cells all at once when it finally gets unstuck. I could give you access to that server if you want to check it out firsthand. -Marshall On May 29, 12:50 pm, William Stein <[email protected]> wrote: > 2009/5/29 Kiran Kedlaya <[email protected]>: > > > > > > > On Apr 14, 3:47 pm, William Stein <[email protected]> wrote: > >> On Tue, Apr 14, 2009 at 12:30 PM, Kiran Kedlaya <[email protected]> wrote: > > >> > I see 100% CPU usage when the notebook is processing a cell.
