[Server] Samba OK ma lento nonostante il gigabit...

[feua]

Salve,

pur essendo la macchina in questione una 7.10 posto qui perchè di fatto è trasformata in server. Si tratta di un P3@1000Mhz e un HD eide da 80GB che utilizzo fondamentalmente come file server. Ho recentemente avuto la necessità di salvare file di grosse dimensioni (fino a 2GB) che poi devo travasarmi sul mio pc con windows xp.

Entrambi i pc sono con scheda di rete a gigabit e in mezzo c'e' uno switch a gigabit e i link sono ok.

Samba per quello che devo fare funziona perfettamente, tuttavia è lentissimo. Utilizzando il teracopy per windows ho scoperto di non superare i 4MB/s quando in ufficio con una rete a gigabit e un server w2003 riesco tranquillamente ad arrivare al limite del disco.

In allegato vi posto un top della macchina linux durante un grosso trasferimento, vi chiedo quindi:

1) Secondo voi un P31000 è troppo lento e mi frena il trasferimento?
Teoricamente no perchè dal top il processo smbd è al 15%...
2) Che sia la rete lenta?
Teoricamente no, entrambe le macchine a giga...
3) Disco lento?
E' un maxtor diamond max plus 9, sul mio pc fisso faceva oltre 50MB/s...
4) Macchina windows lenta?
E' un core due duo con dischi sataII...

Qualche idea?
Cosa posso verificare?

Grazie in anticipo per chi mi vorrà aiutare e buon natale.

da quello che posso vedere la ram è un po' pochina, infatti il server ti swappa.
potresti provare ad aggiungere un po' piu' di ram, comunque lascio la parola a chi ne sa piu' di me

[feua]

Grazie per il suggerimento della ram, tempo di reperirla e provo.
Nel frattempo ho fatto una prova di trasferimento disco-disco sul server e va un po' più veloce (6MB/s contro i 3 via rete) ma siamo comunque molto molto bassi. Sembra quindi un problema di macchina.
Vi posto un top preso durante la copia, ovviamente avevo tirato su l'interfaccia grafica per fare un po' di prove.

Altri suggerimenti?

Grazie.

[Alien321]

consiglio che nn centra molto con il problema, prova a usare htop invece del top te ne innamorerai....

prova un hdparm -tT /dev/[disco]

se viene visto come sd... potrebbe darti un errore

per testare le prestazioni di rete prova anche iperf

[Miguel77]

sul disco che filesystem usi?

[feua]

Grazie per i vari consigli...

Be 14.45 MB/sec non cached è cristallino come risultato l'hd è lento il mio che è na messa schifezza fa:

Timing cached reads:  248 MB in  2.00 seconds = 123.98 MB/sec
Timing buffered disk reads:  90 MB in  3.12 seconds =  28.81 MB/sec

per cui scordati il gigabit...^^
Sarebbe da vedere se l'hd è configurato bene ma di solito si
fai un sudo "hdparm /dev/hda" e vediamo se il DMA ecc è attivo...

Il DMA sembra abilitato... secondo voi allora la soluzione è disco / ram?

Grazie

[feua]

Risolto in parte,

scrivo qui la soluzione parziale:

1) Ho raddoppiato la RAM, ora a 512MB non swappa più
2) Ho formattato tutto e installato la 8.10

Ora durante trasferimenti via samba il processo smbd sfiora il 70-80% della cpu e il transfer rate si attesta sui 12-13 MB/s. Credo che il P3 1000 di più non riesca proprio a pompare.

Ulteriori suggerimenti per aumentare le performances di samba?

Grazie.

[Alien321]

Le prestazioni di samba nn centrano nulla è L'HD che è LENTO, pui mettere anche un tera di ram le cose nn cambiano....devi cambiare l'HD e prendere uno + performante....

[feua]

ri-ciao a tutti e buon anno!

@Alien321
Grazie della tua opinione. Il problema è che quel disco li montato sul mio pc fisso core 2 duo ha prestazioni decisamente maggiori (minimo 50MB/s in lettura, in genere fa anche qualcosina in più. Ho paura che sia proprio il chipset di quella scheda madre lento oppure proprio il processore, oppure può darsi che sia il driver di ubuntu che non lo sfrutta a dovere.

Resta il fatto che da quando ho raddoppiato la ram le prestazioni sono aumentate sensibilmente, probabilmente prima swappava limando ulteriormente le prestazioni. Adesso non swappa più e l'HD è più libero, vorrei capire se con questo HW (disco a parte) sono già al top oppure è possibile spremere ancora qualcosa ottimizzando qui e la.

E' capitato a qualcuno? Allego lspci e dmesg della macchina.

Ogni opinione e suggerimento è bene accetta
Grazie della vostra pazienza

Hai provato a rifare un "sudo hdparm -tT /dev/hda" ? Dopo aver messo + ram?

[feua]

Più o meno uguale a prima...

Codice: Seleziona tutto

 sudo hdparm -tT /dev/sda

/dev/sda:
 Timing cached reads:   112 MB in  2.00 seconds =  55.95 MB/sec
 Timing buffered disk reads:   64 MB in  3.05 seconds =  21.01 MB/sec

Ho appena fatto un test trasferendo da via samba da linux a windows un file di grosse dimensioni e la velocità è compresa tra i 7 e i 9 MB/S.

[Yota73]

Anche io ho lo stesso problema.
Installato piu' volte su
AMD 4850e
2Gb RAM
4 Hard Disk SATA (RAID 5)
1 Hard Disk IDE (BOOT)
Filesystem: ext3 (ho provato anche reiser)

Dalle prove che ho fatto succede questo:
- Appena installato e ,occasionalmente, a qualche riavvio il trasferimento dati dall'IDE ai SATA oppure dall'IDE alla LAN Gigabit  viaggia attorno ai 30Mb/s
- Dopo un po che è acceso oppure dopo qualche settimana che è installato non c'e' piu alcun verso che il transfer rate superi i 9Mb/s. Tutto questo sempre solo sul canale IDE perche' i SATA vanno a 70Mb/s anche in rete !!!

Se qualche anima pia può aiutare anche me gli sarei eternamente grato  >:(


Domenticavo! Provato SUSE 11.1 e non sembra essere afflitto da questo problema ma ormai a forza di prove conosco come le mie tasche ubuntu e non vorrei dover ricominciare tutto da capo
