Hi guys,
after 22 days of dummy conversation with official Synology support my patience is on the edge.
Symptoms:
Synology Drive unexpectedly decreases transfer speed of sync just for WAN. The LAN sync is OK. Nothing has been changed in the architecture (NAS, WAN, LAN).
Basics- NAS side:
DS1813+, DSM 6.2.1-23824 Update 6 (last ver)
Target Volume - RAID1 by 2x Seagate ST1000NC001-1DY162
Indexing - on, Traffic control - off, Docker with iperf3
Basics- WAN/LAN side:
WAN: 1Gbps/150Mbps FTTH, Router Hua HG8245U (1Gbps/1Gbps)
LAN side: Second Router Cisco RVS4000 (1Gbps/1Gbps), all wired through Cat6a, 10GB switch
HDD benchmarking (ssh,hdparm -t /dev/sda & b) : (RAID1 on Volume 1 - Synology Drive):
/dev/sda: Timing buffered disk reads: 474 MB in 3.00 seconds = 157.78 MB/sec
/dev/sdb: Timing buffered disk reads: 444 MB in 3.01 seconds = 147.71 MB/sec
Test data sample:
1. Data sample for the tests (LAN, WAN, except iperf3)- mixed data from 110MB to 85KB in total 546MB (110 files in 61 folders)
2. Data sample for the tests (LAN, WAN, except iperf3)- single file 1,51GB
To avoid trouble on my WAN, finished benchmarking (except NAS) Download/Upload to LAN:
A. From Google Drive to LAN device AVG speed of D/U:
1. Data sample 328Mbps/92Mbps
2. Data sample 560Mbps/139Mbps
B. HTTPS direct server (different site, different ISP), to LAN device AVG speed of D/U
1. Data sample 478Mbps/124Mbps
2. Data sample 612Mbps/140Mbps
NAS transfer speed Results:
LAN speed test (averages), direct transfer of the Data samples trought LAN to NAS:
by iperf3: avg 687Mbps
by SMB from LAN (Win10) to NAS: 552Mbps
Synology Drive sync by LAN has same results
WAN speed test (Read/Write averages):
by iperf3: avg 22Mbps ..... NAS to NAS - directly from iperf Docker container Terminal to iperf Docker container Terminal through WAN IP address
by iperf3: avg 26Mbps ..... from iperf client hosted on LAN (Win10) to iperf Docker container Terminal on NAS (WAN IP address of NAS has been used as target)
same speed rates for Synology Drive sync (Read or Write) from WAN devices to NAS (100Mbps/100Mbps guaranteed symetric data connection). Same speed also for cellular data Drive sync (of course it's no guaranteed line).
by FreeFileSync SW (SFTP): 112Mbps .... upload from FreeFileSync clinet (Win10) to NAS (WAN IP address of NAS has been used as target)
Different WAN speed test :
Shared folder created on same NAS Volume synced with Google Drive by Synology Cloud Sync services.
1. Data sample for the test uploaded to Google Drive from LAN, then synced to Synology (by the WAN) with avg speed of NAS Write 296Mbps.
Same index (on) services on the Volume. Same utilization of CPU/RAPM. It is >10x faster like direct Synology Drive.
Ookla WAN speed test is running every time ... avg 860/145Mbps for the WAN. No anomalies. Of course the Download sometimes is dynamic (aggregation), but never under 560Mbps. But Upload is still in awaiting speed line.
All external services like Google Drive, One Drive, ... are providing perfect transfer speed for D/U between LAN/WAN sync tasks .
Same results with standard Synology packages in usage or with feew of them (can't stop because Synology or Testing purposes):
(you can't stop these) Universal search, Pearl, Recover Root Shell, Node.js v4, Java7 + (testing purposes) File station, Drive, Cloud Sync, WebDAV Server
And of course - no heavy traffic on LAN/WAN during the scenarios.
So, how I can stabilize the WAN speed connection to NAS, from Synology Drive or DSM point of view?
Thx for a help
