Here at the school district I was running into a problem where if several Mac OS X wireless clients logged into the network at once, everything slowed down to a crawl. After researching the problem, it looked like the user’s Library and Microsoft User Data folders were causing the problem. I tried turning on OS X’s home folder syncronization, but that didn’t work very well, and filled up our older computers fast. The solution I found was to locally cache the user’s Library and Microsoft User Data folder. To do this, create a symbolic link from the user’s networked ‘Library’ folder and point it to a local source. I chose \/tmp\/UserCache\/username\/Library. Here is the login script I created to automate the process:<\/p>\n
