It will run, but won't make use of the hyperthreading (hyperthreading is a form of SMP). Regards Henrik On Monday 07 July 2003 04.22, Wei Keong wrote: > Hi All, > > Good day.

In fact, there could be a performance hit if, as in FreeBSD (pre 5.3), the scheduler is not "intelligent", and allocates processes in a round robin fashion: the best possible scenario in a SMP system is if the squid process gets its own CPU, and the other(s) get most of the other system tasks; in hyperthreading, CPU allocation is overloaded, so anonymous tasks could get allocated to a CPU that is also running Squid, causing Squid to get swapped out. Of course, when scheduling allocation and controls improve on such systems, there may be benefits, but this appears to be some way off at present.

Hi All, Good day. Just wondering if anyone has tried running Squid 2.4/2.5 on hyperthreaded Intel P4 CPU? Could this be the interim solution?

Squid-3.0 will not improve in this aspect. The hope is that Squid-3.0 will be somewhat faster than Squid-2.5, but it sill will use a single CPU thread only. There is much thought going on in how to make Squid SMP scaleable, but so far all ideas requires rather far going changes to the internals of Squid, more than what is practically possible in one development cycle. The Squid internal design is gradually being refined and cleaned up however, and it is not unlikely there at some time will be a SMP capable Squid available, it won't be Squid-3.0 however, and quite likely not Squid-3.1 either (at least not fully). The Squid-3.0 release is selected as a middleground, with a whole lot internal redesign most users won't notice but preparing for the development of more visible news in later releases, combined with a reasonable amount of noticeable new features much asked for. Notice: Very little of the founded work in Squid-3.0 is performance related. Allmost all is functionality related. The performance related work and research has been done almost entirely by individual developers own interest alone. Regards Henrik

That's maybe a good suggestion for Squid v3.0.. multitasking = work with multiple CPU's That should be something nice, as Squid is almost always used on servers...and most server have multiple CPU's. :) Bart Riza Tantular wrote: Thanks for your suggestions :) - Original Message - From: "Ralf Hildebrandt" <[EMAIL PROTECTED]> To: "Riza Tantular" <[EMAIL PROTECTED]> Cc: <[EMAIL PROTECTED]> Sent: Sunday, July 06, 2003 6:17 PM Subject: Re: [squid-users] Squid with dual processor .. * Riza Tantular <[EMAIL PROTECTED]>: I would to ask, how to run squid with dual processor ?
