have you tried to delete and rebuild/recreate the cache dirs? if i experienced such issues it was mostly caused by incomplete/defective files in cache. Some changes of the parameters make it neccessary to recreate your cache dirs. http://doc.pfsense.org/index.php/Squid_Package_Tuning please also take a look at http://forum.pfsense.org/index.php?topic=54546.0 the mentioned bonnie benchmarks are only interesting on random read/write in regard to squid ;-) as you can see there the latency of random seeks ( up to 3 seconds :O ) is a bit umh , thats the point. Squid does random access. UFS + softupdates can make a difference. Rising up the kernels dircache too, but as i understand not in your case, 128MB squid cache-dir is not much. another point can be to rise up the minimum caching object size. caching serval bytes ( up to the blocksize of your FS/Disk) can be much more stress than load them from new. depends on your cache policy and the update intervals for cached objects. m. -- = = = http://michael-schuh.net/ = = = Projektmanagement - IT-Consulting - Professional Services IT Michael Schuh Postfach 10 21 52 66021 Saarbrücken phone: 0681/8319664 @: m i c h a e l . s c h u h @ g m a i l . c o m = = = Ust-ID: DE251072318 = = =
