...est 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: 2.462625 1.449550 Average: 0.000049 0.000029 Delete file performance BtrFS Ext4 Total times: 3.312796 0.997946 Average: 0.000066 0.000020 The results were measured on a x86_64 server with 4 cores and 2 SAS disks.

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...

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] call second::second ; ctor call And in ctor ................................................................................ 012B19E0 mov...

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

...ven if only the first 'on.exit' was called, it was still executing the one with the 'add=T'. I am using Version 1.3.0 (2001-06-22) on Windows 2000. Here is a small sample of what is happening. The function conditionally sets up the on.exit, and as you can see, each time the 'second' one is setup, it just keeps adding to what is output: > x.func <- function(x=0){ + on.exit({cat('first exit call\n')}) + if (x == 1) on.exit({cat('second exit call\n')}, add=T) + invisible(NULL) + } > x.func(0) # only the 'first' exit first exit...

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) af...

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 le...
