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:

I'm not mathematically gifted, but shouldn't 957%60 be 15 remainder 57? Google and my desktop calculator certainly think so. So where am I going wrong here? The following code exten => 7,1,Verbose(Context: ${CONTEXT} Exten:${EXTEN}) same => n,Set(myNum=957) same => n,Set(sec=$[REMAINDER(${myNum},60)]) same => n,Set(sec=$[ABS(${sec})]) same =>

Hi all, When I ran the experiments to compare an application''s execution time in both a domU (named cctest1) and a native Linux machine (named ccn10), I noticed the application executes faster in domU. The host of the domU (named ccn9) and ccn10 are two nodes of a cluster and they have same hardware configurations. domU (cctest1) is created by exporting loopback files from dom0 on

An interesting results.

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

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) after waiting for about 25 seconds. So 42 seconds is too high. In

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

The deflation request to the target, which isn't unaligned to the guest page size causes endless deflation and inflation actions. For example, we receive the flooding QMP events for the changes on memory balloon's size after a deflation request to the unaligned target is sent for the ARM64 guest, where we have 64KB base page size. /home/gavin/sandbox/qemu.main/build/qemu-system-aarch64

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);
