You may also have to change your kern.maxfiles parameter to say about 8192 or 16384. > in my kernel config file?

Well if your proxy serves less than 30 requests per second, then ufs storage is fine. However if your demands are above 30 requests per second, then either diskd and aufs will be good. However you may need to tweak your kernel to implement diskd for FreeBSD. Try using these in your kernel config file: options MSGMNB=8192 # max # of bytes in a queue options MSGMNI=40 # number of message queue identifiers options MSGSEG=512 # number of message segments per queue options MSGSSZ=64 # size of a message segment options MSGTQL=2048 # max messages in system options SHMSEG=16 options SHMMNI=32 options SHMMAX=2097152 options SHMALL=4096 options MAXFILES=16384 Also, I really like the COSS storage system in Squid. Even though, the docs and FAQs say that it may not be ready for production servers, I definitely suggest you to try it out. In fact, I am using it for 2 of my FreeBSD servers which serves about 100 - 200 requests per second. And I have to say that it's really fast and stable. It has not crashed or suffered any kind of problems since the past 4 months. To get the best results, use it in conjunction with either diskd or aufs. > Thanks. > Dave. > > - -- With best regards and good wishes, Yours sincerely, Tek Bahadur Limbu (TAG/TDG Group) Jwl Systems Department Worldlink Communications Pvt.
