...from 1.2.9 to 1.4.4. We are now noticing slowdown of batch jobs in Oracle, while hotbackup runs faster. One thing we saw is that journal mode changed from write-back to ordered, as we don't specify journal mode during mount. Oracle sees this as slowdown based on higher IO latency, going from 6-8ms to 13-15ms for single block IO. Total IO throughput has dropped. Can this be caused by the journal mode being ordered? Ulf.

...oes not like the quick line shuffling and call volume. We get the following problems randomly: 1. menu stops working 2. transfer key stops working 3. Line 1 LED gets stuck 4. Voice 'gaps' (blackouts) for 4-5 seconds 5. The phone also completely locks up regularly 6. ping response goes from 8ms to 3000ms (after which the phone locks up) Wondering which operator phone would work best. I have the following choices: 1. Linksys SPA 932/962 with attendant console 2. Polycom 601/650 with attendant console I cant confirm online whether the BLF functionality will work with Asterisk 1.2.26. Is...

Keir, It''s a resending patch for the timeout mechanism to deal with the shared interrupt issue for vt-d enabled hvm guest. We modify the patch following your comments last time and make some other small fix: 1) We don''t touch the locking around the hvm_dpci_eoi(). 2) Remove the HZ from the TIME_OUT_PERIOD macro which may confuse others. 3) Add some

...nt reading, large extents are good, because they minimize seeks in sequential reads. But there will be diminishing returns when the extent gets bigger than the size of a physical disk cylinder. For instance, modern disks have a data transfer rate of (about) 200MB/s, so adding one extra seek (about 8ms) in the middle of a 200MB extent can''t possibly slow things down by more than 1%. (And, that''s the worst-possible case.) But, large extents (I think) also have costs. For instance, if you are writing a byte into the middle of an extent, doesn''t Btrfs have to copy the e...

I am experiencing audio ticks when doing calls from SIP or console to ISDN. Calls. Everything appears fine when doing ISDN->ISDN or SIP->SIP. Console calls results in 5-8 ticks a second, SIP calls are dependent on buffer size - 16ms are 1 tick a second, 8ms are 2-3 ticks a second. I recently moved the ISDN board and software to an upgraded PC with the exact same software configuration - prior to moving the audio was fine. There are no IRQ conflicts, and just for the heck of it I have experimented with moving the card to another PCI slot, enabling/di...

...these links for your edification. http://kbase.redhat.com/faq/docs/DOC-15355 http://bugzilla.redhat.com/show_bug.cgi?id=448130 Problem is kernel threads cannot create or assign an io context as there is no api in the kernel available to do so, so each is given a different context and there is an 8ms latency between switching contexts. The knowledge base article recommends disabling this latency to get around it, but in doing that you might as well just use the deadline scheduler. Some other interesting tidbits for those using NFS. NFS with many nfsd threads will create a lot of file system f...

Hi. I have been searching through old threads and various forums, but can't seem to find out what the consensus view is here on the best type of FXO hardware to use for a home asterisk implementation. Specifically, should I buy a FXO ATA like the Sipura 3000, or a PCI form factor port like the Digium TDM400 series. I have read horrible things about problems with the X100P, so I have ruled

Hi WOW! Is Rails 3 another interesting learning curve. Just when I think I have a general working knowledge of Rails 2 ... things change. I''m trying to replicate the following in Rails 3: <%= link_to_remote image_tag("creditcard.png", :border => 0), :url => {:action => :make_payment, :type => "Credit", :id => @appt.id },

Pre-fletching on the file and device level has been disabled yielding good results so far. We''ve lowered the number of concurrent ios from 35 to 1 causing the service times to go even lower (1 -> 8ms) but inflating actv (.4 -> 2ms). I''ve followed your recommendation in setting primarycache to metadata. I''ll have to check with our tester in the morning if it made a difference. I''m trying to understand why we''re seeing getting a lot of read requests to di...

...est case have 2 sites with t1s. I''m setting speed much lower to allow for some phone traffic that comes off before I get it. During the tests there is no phone use. I set to do iperf between sites between sites both direct and therough the vpn. With no traffic ping time direct is about 8ms and 10ms via vpn. With saturating direct traffic . Direct ping is about 40-50 ms vpn ping is about 50ms With saturating vpn traffic Direct ping is about 15-30ms vpn ping is about 18-250ms Ping times are very erratic particular in the one bad case. Some times pings via vpn are over a second. T...

I have a 12 channel PRI with SNOM 190's and asterisk CVS from January. Most calls are fine, all incoming calls are fine, but I am getting echo on a significant number of outgoing calls. The person on the other side hears a perfect call, but the SIPphone side gets to hear themselves. It happens 100% of the time to some numbers (outgoing only), and only sporadically to others. Has anyone

Hi Is it possible to subset an n-dimensional array by a vector of n dimensions? E.g. assume I have > x <- array(1:24, dim=2:4) > x[1,1,2] [1] 7 > dims <- c(1,1,2) I would like a function that I can supply x and dims as parameters to, and have it return 7. Also, I would like to do something like: > x[1,1,] [1] 1 7 13 19 > dims2<- c(1,1,NA) And have a function of x and

All, I have a Cyberpower UPS that I have been working with for about a year. I have used NUT in the past with good results, but as of late have been seeing issues with nut talking to the UPS.
