Poor creat/delete files performance
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:

Problem with REMAINDER? 957%60 be 15 remainder 57 not 15 remainder -3 ?
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 =>

question about disk performance in domU
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

Mysql 6 second rounding
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

[LLVMdev] Microsoft constructors implementation problem.
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

[LLVMdev] [PATCH] FoldingSetNodeID: use MurmurHash2 instead of SuperFastHash
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.exit processing
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'.

Exact purpose of network.ping-timeout
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

Puzzled by what Rprof is telling me
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

[PATCH] virtio_balloon: Fix endless deflation and inflation on arm64
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.

llvm-cov: Combined report for multiple executables
Hi! I am trying to get a combined coverage report from multiple

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:
