HI, Need some help from the group. we are curently on SQUID 2.5-12. Does the 'file desc currently in use' means, number of connections to/from squid? We happened to experience slowness in accessing the net when the file desc numbers grows.Does limiting the file desc helps to improve performance. How do I do that? Which log should I refer to check whether there is any problem? Please help. Thank you so much. File descriptor usage for squid: Maximum number of file descriptors: 1024 Largest file desc currently in use: 300 Number of file desc currently in use: 248 Files queued for open: 0 Available number of file descriptors: 776 Reserved number of file descriptors: 100 Store Disk files open: 2 __________________________________________________ Do You Yahoo!?
