Hi, I have a pair of forward proxy's (Squid 2.6STABLE 21/EL5 averaging about 500-600requests per minute currently. All caching has been disabled. Some users are reporting high latency and slow browsing. Below is a snapshot of stats from Squid. Could someone tell me if anything stands out that would cause a problem? Service times look to be acceptable to me, but perhaps I am looking at them incorrectly? You can also view a graph of 5min service times at http://thunder.jbdesign.net/~jbaird/servicetimes.png Squid Object Cache: Version 2.6.STABLE21 Start Time: Sun, 27 Jun 2010 15:17:41 GMT Current Time: Mon, 28 Jun 2010 20:04:09 GMT Connection information for squid: Number of clients accessing cache: 5 Number of HTTP requests received: 848091 Number of ICP messages received: 0 Number of ICP messages sent: 0 Number of queued ICP replies: 0 Request failure ratio: 0.00 Average HTTP requests per minute since start: 491.2 Average ICP messages per minute since start: 0.0 Select loop called: 20321720 times, 5.097 ms avg Cache information for squid: Request Hit Ratios: 5min: 0.0%, 60min: 0.0% Byte Hit Ratios: 5min: 0.7%, 60min: 1.0% Request Memory Hit Ratios: 5min: 0.0%, 60min: 0.0% Request Disk Hit Ratios: 5min: 0.0%, 60min: 0.0% Storage Swap size: 0 KB Storage Mem size: 288 KB Mean Object Size: 0.00 KB Requests given to unlinkd: 0 Median Service Times (seconds) 5 min 60 min: HTTP Requests (All): 0.06286 0.05633 Cache Misses: 0.06286 0.05633 Cache Hits: 0.00000 0.00000 Near Hits: 0.00000 0.00000 Not-Modified Replies: 0.00000 0.00000 DNS Lookups: 0.00573 0.00669 ICP Queries: 0.00000 0.00000 Resource usage for squid: UP Time: 103588.205 seconds CPU Time: 493.167 seconds CPU Usage: 0.48% CPU Usage, 5 minute avg: 1.35% CPU Usage, 60 minute avg: 1.63% Process Data Segment Size via sbrk(): 17996 KB Maximum Resident Size: 0 KB Page faults with physical i/o: 0 Memory usage for squid via mallinfo(): Total space in arena: 18128 KB Ordinary blocks: 14029 KB 213 blks Small blocks: 0 KB 0 blks Holding blocks: 356 KB 1 blks Free Small blocks: 0 KB Free Ordinary blocks: 4098 KB Total in use: 14385 KB 78% Total free: 4098 KB 22% Total size: 18484 KB Memory accounted for: Total accounted: 4184 KB memPoolAlloc calls: 116115679 memPoolFree calls: 116109502 File descriptor usage for squid: Maximum number of file descriptors: 1024 Largest file desc currently in use: 544 Number of file desc currently in use: 408 Files queued for open: 0 Available number of file descriptors: 616 Reserved number of file descriptors: 100 Store Disk files open: 0 IO loop method: epoll Internal Data Structures: 57 StoreEntries 57 StoreEntries with MemObjects 26 Hot Object Cache Items 0 on-disk objects Thanks, Josh
