skyrocketing = using our maximum link download bandwidth. This machine is only proxying. Not being a firewall, not a router, nor a gateway. It has access to the internet through our gateway/firewall (pfsense). Lots of LAN clients are connected to the proxy, this is their only way to the internet. 1 interface, debian linux. EXT4 FS. CPU/MEM usage is always stable. Clients use it explicitly or via wpad. Never transparently. Now I'm using 3 workers, because 1 is not enough and we have spare cores. It's a VM machine with netapp storage. lots of raid disks. SQUID was running perfectly without cache_dirs. I think squid is downloading and redownloading the same files over and over again because: 1- these are segmented downloads and range_offset_limit is set to NONE for these files. 2- it can't store the downloaded files on the cache but I don't know why! 1457358960.737 8399 10.23.0.63 TCP_SWAPFAIL_MISS/206 1058138 GET http://au.download.windowsupdate.com/c/msdownload/update/software/uprl/2013/10/ie11-windows6.1-x64-en-us_ddec9ddc256ffa7d97831af148f6cc45130c6857.exe - HIER_DIRECT/201.30.251.43 application/octet-stream 1457358987.869 22464 10.88.10.5 TCP_SWAPFAIL_MISS/206 1416417 GET http://au.download.windowsupdate.com/d/msdownload/update/software/secu/2016/02/ie11-windows6.1-kb3141092-x64_0f7a98b9dc9f5c7ac73f6f543bf004a15e4d7be8.psf - HIER_DIRECT/201.30.251.26 application/octet-stream Squid Object Cache: Version 3.5.15-20160301-r13999 Build Info: Service Name: squid Start Time: Fri, 04 Mar 2016 21:15:47 GMT Current Time: Mon, 07 Mar 2016 18:14:37 GMT Connection information for squid: Number of clients accessing cache: 4543 Number of HTTP requests received: 7305505 Number of ICP messages received: 0 Number of ICP messages sent: 0 Number of queued ICP replies: 0 Number of HTCP messages received: 0 Number of HTCP messages sent: 0 Request failure ratio: 0.00 Average HTTP requests per minute since start: 1765.1 Average ICP messages per minute since start: 0.0 Select loop called: 365044476 times, 11.146 ms avg Cache information for squid: Hits as % of all requests: 5min: 22.0%, 60min: 21.2% Hits as % of bytes sent: 5min: 3.9%, 60min: 7.3% Memory hits as % of hit requests: 5min: 2.5%, 60min: 2.9% Disk hits as % of hit requests: 5min: 28.1%, 60min: 26.8% Storage Swap size: 179951936 KB Storage Swap capacity: 45.1% used, 54.9% free Storage Mem size: 4194176 KB Storage Mem capacity: 100.0% used, 0.0% free Mean Object Size: 46.07 KB Requests given to unlinkd: 0 Median Service Times (seconds) 5 min 60 min: HTTP Requests (All): 0.06514 0.07007 Cache Misses: 0.09730 0.10075 Cache Hits: 0.00055 0.00055 Near Hits: 0.06521 0.06757 Not-Modified Replies: 0.00055 0.00055 DNS Lookups: 0.00019 0.00019 ICP Queries: 0.00000 0.00000 Resource usage for squid: UP Time: 248329.183 seconds CPU Time: 21525.705 seconds CPU Usage: 8.67% CPU Usage, 5 minute avg: 52.35% CPU Usage, 60 minute avg: 47.90% Maximum Resident Size: 85809792 KB Page faults with physical i/o: 104 Memory accounted for: Total accounted: 164356 KB memPoolAlloc calls: 1801863396 memPoolFree calls: 1811836496 File descriptor usage for squid: Maximum number of file descriptors: 81920 Largest file desc currently in use: 6157 Number of file desc currently in use: 8216 Files queued for open: 0 Available number of file descriptors: 73704 Reserved number of file descriptors: 500 Store Disk files open: 11 Internal Data Structures: 25054 StoreEntries 391 StoreEntries with MemObjects 96086 Hot Object Cache Items 3905959 on-disk objects Best Regards, -- Heiler Bemerguy - (91) 98151-4894 Assessor Técnico - CINBESA (91) 3184-1751 Em 07/03/2016 14:33, Eliezer Croitoru
