In Thecus N2560 as a ZurmoCRM Application Server Performance Report, I see N2560 could run as fast as Shuttle X50V2. Therefor, embedded Linux shall be as fast as desktop Linux.
Although QNAP TS-251 has the latest Celeron J1800 and comes with the latest QTS 4.1, it is still using outdated PHP 5.3.28 and MySQL 5.1.36. Let’s see how fast it could beat with previous Atom D2701 models.
Processor, RAM, and Linux Difference
TS-251 has a J1800 at 2.41GHz which may burst to 2.58GHz; N2560 has a CE5335 SoC at 1.6GHz; TS-119PII is a Marvell 88F6281 at 1.6GHz; AS-602T and TS-269L is Atom D2701 at 2.13GHz; the only desktop Shuttle X50V2 is Intel Atom D510 at 1.6GHz.
J1800 is based on Bay Trail which is part of the Atom family. It has 2 cores but without hyper-threading technology which means it may serve and 2 threads only. The 1MB cache size is still the same to D2700 but support for 8GB RAM which is double to D2700. CE5335 SoC and D2700 are based on Berryville and Cedar Trail respectively. Both have 2 cores with hyper-threading technology. The former has 512KB L2 Cache and supports 32-bit physical addressing while the latter has 1MB and supports 36-bit. Marvell 88F6281 has 32-bit instruction set. D510 is very similar to D2700 expect running at a lower frequency.

I connect NAS to computer directly. Install ZurmoCRM and setup with build-in demo data. Shuttle X50V2 is setup with ISO image from TurnKey Linux Zurmo. Then use Firefox to list all contacts. There are 28 contact records provided from ZurmoCRM demo data.
To satisfy requirement, I also manually edit Qthhttpd.sh in QTS, and php.ini in Debian and ADM to increase memory_limit from 128M to 256M with one exception: I keep everything as default in TS-251. Please reference Asustor ADM Configuration and Executable Files, QNAP QTS Configuration and Executable Files, and TurnKey Linux Configuration and Executable Files to find the path. I also edit php.ini and my.cnf on ThecusOS. Please refer to Prerequisite Before you Install ZurmoCRM on Thecus NAS running ThecusOS 6 for detail.
All unnecessary background process and programs are disabled.
With the right cache system required by Zurmo, it may improve performance.
Alternative PHP Cache helps to execute faster by caching compiled codes and eliminating the overhead of compiling the same code again. It is supported on certain ADM. QTS or TurnKey Linux doesn’t have this extension by default.
Running Memcache extension and memcached service together helps to cache database result and lower database loading in LAMP. It is supported on Thecus Apache_126.96.36.199_x86.mod and certain ADM but not supported on QTS nor TurnKey Linux.
According to my MTU test, I keep it to use default 1500.
I measure time to load 1 and 5 contacts in a single login session. The 5 contacts are loaded in different tabs in the same Firefox. Therefore, it use only one thread and won’t begin to load the next until finish. If you are confused or interested in the relationship of LAMP, thread, multi-core processor, hyper-threading, How Multi-Core Processors Accelerate your LAMP Applications provides detail explain in plain English.
TS-251 is almost as fast as the second best configuration for N2560 with MySQL 5.5.14. It match Shuttle X50V2 without Alternative PHP Cache nor memcached. N2560 with PHP 5.5.11, APCu, memcached, and a newer MySQL 5.6.17 is even faster than TS-251.
Compared to TS-269L, it is a huge improvement. More than 50% faster!
The new Bay Trail J1800 on TS-251 is definitely a plus to NAS running power hungry LAMP applications. But as I have mentioned in QNAP TS-251 File Transfer Performance Report, the real shine is Virtualization Station.
