Opening a folder can be done in two ways - either just open it with SELECT, or open it and download all message headers. Opening a folder with 12000 messages (my qmail folder is that big) takes just a second or two with Binc IMAP. Mozilla downloads all message headers the first time you connect to a new server. This download will take just as long time with any IMAP server that has little overhead with parsing the mime documents. The main bottleneck is the bandwidth of your Internet connection. Downloading 12000 message headers might means several megabytes travel across the network. After you opened the 12000 message folder, if you quit mozilla and start up again, was is equally slow to open the same folder again?
