Hi, I write a script for cyradm to set the ACLs for all the users, like this: setaclmailbox user.perez cyrus kxa setaclmailbox user.pirat cyrus kxa setaclmailbox user.plouvier cyrus kxa setaclmailbox user.pruche cyrus kxa setaclmailbox user.seltani cyrus kxa setaclmailbox user.serre cyrus kxa setaclmailbox user.solers cyrus kxa ...[400 accounts]... I then feed the script to cyradm. But after 10 lines, the execution suddenly slows down to a crawl, and only one "setaclmailbox" every 10 or 20 seconds is executed. I'm running a unified cyrus murder 2.3.7, with 2 imap servers and 1 mupdate server. I ran the script only on one imap server, and all the accounts belong to this server. These are the logs I see on the mupdate server. The imap server keeps connecting/disconnecting from the mupdate server, and the mupdate server seems to spend a lot of time in either cmd_find or cmd_set.

Can anybody explain this to me and help me debug it? Or is there another way to set hundreds of ACLs in a row?
