hello Arnaud,
sorry, me again, I'm your nightmare :-P
please, if you have time, to do a test of the Synopse with my patches www.dellapasqua.com, one is for mem manager and rtl fillchar, copymem, etc, another is for zlib,
in alternative, where can I find the Synopse benchmark, so to test the speed and reliability?
Btw. do you like extend the IPP patches with other functions as Math, Vectors, etc.?
A bientot.

You can run the SQLite3\TestSQL3.dpr regression tests, and check the numbers reported.
Note that mORMot units try to avoid memory allocation as much as possible for most used code (e.g. JSON production or parsing), so depending on the process, the heap manager won't have a big effect.
Why not statically include the code as asm source, or at least .o files?

because Intel license permits to redistribute under DLL forms :-\ (if I read correctly)

indeed, the results are similar (Intel MM is good for many threads concurrently):
Using IntelTBB
1.1. Low level common:
Total failed: 0 / 10,952,515 - Low level common PASSED 2.45s
1.2. Low level types:
Total failed: 0 / 733,788 - Low level types PASSED 173.84ms
1.3. Big table:
Total failed: 0 / 886,592 - Big table PASSED 1.30s
2.11. DDD shared units:
Total failed: 0 / 80,388 - DDD shared units PASSED 462.14ms
Without IntelTBB
1.1. Low level common:
Total failed: 0 / 10,951,964 - Low level common PASSED 2.41s
1.2. Low level types:
Total failed: 0 / 734,580 - Low level types PASSED 239.36ms
1.3. Big table:
Total failed: 0 / 886,427 - Big table PASSED 1.39s
2.11. DDD shared units:
Total failed: 0 / 80,388 - DDD shared units PASSED 991.26ms
(btw. I have used SynSQLite3Static, but the multithreaded test doesn't run, any hint?)

do you think it's possible to convert the DLLs in one OBJ, maybe using objconv AgnSoft? It's a very hard task, no?

it's open source:
"Threading Building Blocks(Intel® TBB) 2017 now under Apache 2.0 license" https://www.threadingbuildingblocks.org/Licensing
Can you compare Intel MM (TBB) against this patch of FastMM-AVX? https://synopse.info/forum/viewtopic.php?id=57&p=4 Goto post #178 (It says is much better that NeverSleepOnThreadContetion)
Offline
FastMM4 22sec
FastMM4-AVX 18sec
IntelPPI+TBB 4sec
(consider that under single thread fastmm performs slightly better than Intel)
Offline
10.0.15063 (win10 creators update)

well, parallelizing the MM is not enough to get better overall performances, all the algorithms should be made with parallel class, as TParallel.For, etc. and not every task can be parallelized. Anyway the cpu near future is the massive multicore enlargement instead of Ghz war. So the direction seems this.

what do you think about a Delphi compiler OPENMP adherence?

@RObyDP,
Could you test in the same conditions BrainMM?

He already tested, but it was a bug in BrainMM and crashed on Win64.

Roberto Della Pasqua:
"BrainMM actually crashes under some circumstances under WIN64, the author will correct it later this year. I did today another test, intel tbb+intel ipp single thread is slighty faster than fastmm4 and many times faster under threads. If the license will be more permissive perhaps we can build a custom LLVM4 object to embed statically."

Hi!
Unfortunately the library has a few critical bugs, which will be fixed, I think, this autumn. Look for example here: https://github.com/d-mozulyov/BrainMM/issues/5
Thanks for attention to my project

Hello Dimitry,
I like ask if your BrainMM is reliable enough to be used for server 64bit 24/7 applications,
does it suffers of mem fragmentation or leaks, troubles at all?
Do you have customer reports of months of work?
Thank you.
Regards.

@RObyDP,
What was the test result of BrainMM for Win32?
Michal
Offline
I don't have tested, but under win32 seems the faster.
Offline
It's really fast (i3-6100T):
32bit, Multicore:
FastMM-AVX (only ERMS enabled) - 18 sec;
BrainMM - 8 sec;
BrainMM should be investigated how good it is on some 24/7 processes, because performance is stellar!
Offline
I'll do a build of IPP+TBB for IA32, and will see how performs.
Offline
but haven't time now, so I trust you about 32bit
