Download uz je jiny kafe=cca 60MB/s. ZFS pool je namountovanej na Linux pres NFS. Sambu nepouzivam a tipuju ze rychlosti by byly o poznani nizsi. Jinak trafik jde pres 1Gb switch a pfSense router (ten ma taky 1Gb sitovku) protoze server je na jiny LAN nez noutas, coz by ale nemelo mit zasadnejsi vliv na rychlost....... Takze asi tak 
)
Tech 60MBps bude asi spis tim NFSkem nebo siti, ne? Kdybys to pustil lokalne do /dev/null, tak ti to da urco vic, ne?
Zdravim, nemel jsem moc casu a pak jsem byl zas par dni pryc takze jsem se k tomu dostal az ted. Ale jak se rika: "better late than never"
Takze: udelal sem naky mereni a tady sou vysledky:

vysledky PO VYPNUTI lz4 komprese pri stejnych testech:
write-speed samy nuly

3221225472 bytes transferred in 67.952542 secs (47404047 bytes/sec) =45MB/s coz je totozne s vysledkem pri zapnute kompresi a potvrzuje to starou poucku ze nahodna (tedy i dobre sifrovana) data uz dale komprimovat nelze
)
CTENI pri vypnute kompresi:
3GB dat ze samych nul

takze disky ctou a pisou tak jak maj a problem je nekde jinde.
Zkusil sem FTP: down 80MB/s a up cca 60MB/s
Taxem udelal par testu:

coz je tech 60MB/s co uz jsem nameril driv
Taxem nahodil iPerf server na pfSense a zkusil zmerit lajnu JEN od noutase k routeru a vyslo mi tohle:

............z cehoz jsem ponekud jelen protoze to je jeste min nez kdyz sel trafik PRES router a jeste dal na server.
Takze jsem zkusil zmerit prutok od routeru (client) primym kabelem na FreeNAS (kde posloucha server):
Client connecting to 172.x.x.x, TCP port 5001
TCP window size: 65.0 KByte (default)
------------------------------------------------------------
[ 8] local 172.x.x.x port 57411 connected with 172.x.x.x port 5001
[ ID] Interval Transfer Bandwidth
[ 8] 0.0-10.3 sec 391 MBytes 38.1 MBytes/sec
coz je taky dost tragicky a i vysledek jaxi postrada logiku.....
Nakonec jsem propojil noutas s FreeNASem natvrdo/naprimo kabelem a vysledek byl 102MB/s down a 63MB/s up. NFS pri tomhle setupu davalo jen o malo mensi hodnoty, takze vic z toho asi nevymacknu, coz je divny protoze vsechny sitovky po ceste jsou 1Gb/s Intel (a ty bejvaj dobry) s vyjimkou NICu na noutasu=ten sem taky hned od zacatku podezrival, protoze to je Realtek coz je proslavena sracka, ktera vesla ve znamost napr. tim ze po chvili max zatizeni jde do kolen a zacne masove ztracet pakety => TCP retransmission a bandwidth jde tim padem do zadeke.... (proto taky vyvojari z PfSense durazne varujou pred cimkoliv od Realteku )
Tady se ale zda ze je v tom Realtek nevinne. Nezda se ani ze by iPerf ukazoval kraviny, zkusil sem spojeni na verejnej 40Gb/s iPerf server v USA a tlacilo to 12MB/s coz zhruba odpovida kdyz moje lajna je 100Mb/s.....
Any ideas ladies and gentlemen??
