Hi list.
I have RedHat 6.2 on P233 with 512 MB of ram and 2 scsi
disks of 9.1 GB 10K RPM.
i run Squid 2.2.STABLE4-8 (from RPM) and my server keep
crushing !.
Before that i had RedHat6.2 with
Squid-2.3.STABLE3.
I desided to do downgrade (the oposit of upgrade) due to
problems with the squid. (it looks like he did not cache anything at all and
keep crushing also).
I looked at the cachemgr and i got this :
Connection information for squid: Number of clients accessing cache: 1394 Number of HTTP requests received: 735901 Number of ICP messages received: 0 Number of ICP messages sent: 0 Number of queued ICP replies: 0 Request failure ratio: 0.00% HTTP requests per minute: 1562.3 ICP messages per minute: 0.0 Select loop called: 6338757 times, 4.459 ms avg Cache information for squid: Request Hit Ratios: 5min: 48.1%, 60min: 54.0% Byte Hit Ratios: 5min: 21.4%, 60min: 27.1% Storage Swap size: 5918083 KB Storage Mem size: 6144 KB Storage LRU Expiration Age: 3.08 days Mean Object Size: 9.92 KB Requests given to unlinkd: 141511 Median Service Times (seconds) 5 min 60 min: HTTP Requests (All): 0.10857 0.04519 Cache Misses: 1.11539 0.94847 Cache Hits: 0.01309 0.01309 Near Hits: 1.00114 0.80651 Not-Modified Replies: 0.00767 0.00865 DNS Lookups: 0.39726 0.20377 ICP Queries: 0.00000 0.00000 Resource usage for squid: UP Time: 28262.346 seconds CPU Time: 9097.600 seconds CPU Usage: 32.19% CPU Usage, 5 minute avg: 21.07% CPU Usage, 60 minute avg: 19.45% Maximum Resident Size: 0 KB Page faults with physical i/o: 330131 Memory usage for squid via mallinfo(): Total space in arena: 108910 KB Ordinary blocks: 103297 KB 22471 blks Small blocks: 0 KB 0 blks Holding blocks: 1360 KB 4 blks Free Small blocks: 0 KB Free Ordinary blocks: 5612 KB Total in use: 104657 KB 96% Total free: 5612 KB 5% Memory accounted for: Total accounted: 82927 KB File descriptor usage for squid: Maximum number of file descriptors: 1024 Largest file desc currently in use: 261 Number of file desc currently in use: 249 Files queued for open: 0 Available number of file descriptors: 775 Reserved number of file descriptors: 100 Store Disk files open: 3 Internal Data Structures: 945175 StoreEntries 1252 StoreEntries with MemObjects 1210 Hot Object Cache Items 596469 Filemap bits set 596543 on-disk objects ok. My question is, do i need to upgrade my servers or maybe i have problems in configuration ? is there any Squid guru in this list that want to make some money out of it ? Please reply ASAP. Thanks, Mike |
