In "Understanding the Linux Kernel" 3rd edition, section 4.7 "Softirqs and Tasklets" it states: "Activation and execution [of defferable functions] are bound together: a deferrable function that has been activated by a given CPU must be executed on the same CPU. There is no self-evident reason suggesting that this rule is beneficial for system performance. Binding the deferrable function to the activating CPU could in theory make better use of the CPU hardware cache. Afte...

...This means the foreign key constraints are still being enforced, and while #disable_referential_integrity doesn''t raise any errors, referential integrity is not being disabled! There is another approach that doesn''t require superuser privs, and that is to use SET CONSTRAINTS ALL DEFERRED, which defers evaluation of constraints until the end of the current transaction. This approach has two requirements. First, it must be issued within a transaction - if there is no current transaction, the statement has no effect. Second, the constraints must have been created with the DEFERRABLE...

Hi all, I'm enjoying using dovecot deliver with qmail+vpopmail+dspam. It works mostly fine, I like the indexing and sieve features with dovecot deliver. I would like to get more details on trouble, the log entry is just : " 2009-11-18_20:38:55.64778 delivery 50833: deferral: " As you see, there no reason for the deferral. How can I make deliver more verbose ? I also have a vpopmail alias issue. Because some domains (sadly) needs a catchall, and to keep using the useful vpopmail alias features, I'm using the following ugly script : " #!/bin/sh email=...

Patch 1 removes CONFIG_SMP Patch 2 removes separate smp_{,r,w}mb()s as a result of patch 1 Patch 4 removes __ia64__ defines from the x86 arch tree Patch 3 is related to patch 4 and changes the VIOAPIC to emulate version 0x20 as a performance gain. It preceeds Patch 4 so as to be more clear about the functional change. Signed-off-by: Andrew Cooper <andrew.cooper3@citrix.com>

Hello, on the application that I''m working on, we are using Thin. The server implements long polling and commands that alter its internal state. Connecting to the long poll is a very fast operation, while updating the state of the server is a relatively slow operation. The long poll connection is held open until there is a change to be sent to the connection. Here is my current

Hi all Is the EventMachine website (www.rubyeventmachine.com) down? I can''t access it from South Africa, and have tried using tor as well with no luck. I''m kinda new to EventMachine, so I first have a lot of examples to work through and reading to do before I start pestering the mailing list with questions. Thanks to everyone who partook in creating the library, so far

...server is, which coincidentally also hosts the mailing lists you are reading right now. After three short hours and (AFAICS) no lost mail we now have the following situation: The mailq on the old mail server now is empty, while the new one is already fighting with stale dns info, unknown users, deferrals and so on. Normal insanity, I'd say. One word to our moderators and/or mailing list administrators: Everything should work as it did on the old machine. If your list *admin* password isn't working anymore, please drop me a mail so we can clear that up. Everybody else: Send even more m...

...could someone be so kind to expleain me it? Any router performing a shaping function should be the bottleneck on the link, and should be shaping slightly below the maximum available link bandwidth. This prevents queues from forming in other routers, affording maximum control of packet latency/deferral to the shaping device.

...ogic/magic? The problem I'm currently unsure of, is how roots would affect refcounts. Should the gcread/gcwrite not be used with stack refs, etc? 1. If root refs are NOT included in the count, then objects of refcount 0 must be tracked in a list of scheduled deletions, but will be continually deferred until the root goes out of scope (the deletion list is filtered during a collection by the roots callback). 2. If root refs ARE included in the count, then this deferral overhead is avoided, at the expense of more refcount increment/decrement costs (on entry and exit from each function). I'...
