Hi, We did some performance test and found the create/delete files performance of btrfs is very poor. The test is that we create 50000 files and measure the file-create time first, and then delete these 50000 files and measure the file-delete time. (The attached file is the reproduce program) The result is following: (Unit: second) Create file performance BtrFS Ext4 Total times:

...7", "sec=3") in new stack -- Executing [7 at fromvoipfone201:6] Verbose("PJSIP/6001-00000007", "1,957,3") in new stack Where is -3 coming from?!? I can flip it around by using ABS to stop people freaking out when they hear a track is "15 minutes minus 3 seconds long", but it's still incorrect, isn't it? (I add the second MATH function to everything I do now to make it an integer as it seems you never can tell with Asterisk, just ignore it!) Any ideas? Thanks.

This is more of mysql question then asterisk :D . Most voip providers use 6 second rounding for costing . My asterisk server stores call cdr's in mysql properly with billsec field containing number of billed seconds . I want to know some function to round this to 6 seconds ( or any custom valud like 30 seconds ) ..Suppose if billsec field is 3 seconds then it should round to 6 seconds , if its 13 second then it should round up to 18 seconds ( for 6sec pulse counting ) . What would be mysql function to do this...

Hi all. I am working on constructors implementation for MS ABI. Itanium ABI has 2 constructor types - base & complete. MS ABI has only 1 type. How it works I'll show on example. class first { public: virtual void g(){} }; class second : public virtual first { public : virtual void g(){} }; When construct instance of second we will have next code push 1 lea ecx,[f]

While I've not reviewed the patch in too much detail, it looks promising. Can you run some end-to-end benchmarks to make sure that cache pressure in the full program or other variables not accounted for in a micro-benchmark don't dominate performance? Specifically the nightly tester includes a number of real programs and machinery to measure total compile time. On Sat, Feb 6, 2010 at 7:09

I have encountered a 'strange' behavior in the 'on.exit' processing. I had a function where I setup an 'on.exit' condition and then later on added to it with an 'on.exit({...}, add=T)'. What appeared to happen is that on subsequent calls to the function, even if only the first 'on.exit' was called, it was still executing the one with the 'add=T'.

Hi, > If you set it to 10 seconds, and a node goes down, you'll see a 10 seconds freez in all I/O for the volume. Exactly! ONLY 10 seconds instead of the default 42 seconds :-) As I said before the problem with the 42 seconds is that a Windows Samba Client will disconnect (and therefore interrupt any read/write operation) aft...

I am using Rprof() to help find ways to improve performance. I found a function whose total seconds and self seconds were large. I replaced it with something else. The something else had a small number of total seconds and self seconds. But the total time did not decrease. I don't understand how that could be, and would appreciate any suggestions. Thanks -Don Details, unfortunately len...

Hi! I am trying to get a combined coverage report from multiple executables. Looking at earlier discussions [1, 2], it looks like this is supposed to work. I am having some difficulty getting this to work as I would expect it to work, however. Following is a simple case to explain: ////////// shared.h #include <string> void Print1(const std::string& msg); void Print2(const

The following code in VirtRegMap.cpp is asserting in the C++ library because back() is called on an empty container: /// addLastUse - Add the last use information of all stack slots whose /// values are available in the specific register. void addLastUse(unsigned PhysReg, MachineInstr *Use) { std::multimap<unsigned, int>::iterator I = PhysRegsAvailable.lower_bound(PhysReg);
