Ho un problema.
Quando copio un file (per ora ho provato da una partizione all'altra dell'HD), le due CPU vanno anche al 100%, rendendo di fatto inutilizzabile il sistema, finché non finisce la copia.
C'è rimedio a questo problema? Perché ho googlato davvero parecchio e a parte trovare qualcun altro con lo stesso problema, nessuno aveva la soluzione.

Grazie :(.

sicuramente avrai provato... comunque la sparo potrebbe essere in pio, posta il risultato di
hdparm -i /dev/tuo_hd
oppure è una macchina virtuale?

Io credo ci sia poco da fare ... ma cosa usi per copiare ?
Io avevo grossi problemi con konqueror di kde 4.2 sulla 13.0 ... prova ad usare cp per vedere se il problema é causato da kde.

non e' che copi su qualche filesystem in userspace che si appoggia a fuse, tipo ntfs-3g?
potrebbe essere quello che ti sovraccarica la cpu...

Intanto grazie per le risposte.
Dunque, ora sono su un altro sistema, quindi non posso postare l'output di hdparm.
Comunque:
- la copia dei file la facevo da KDE (versione ultima della 13.1) sia usando Dolphin, sia usando il "cp" da riga di comando... stesso problema;
- ora l'unica cosa che ricordo dell'"hdparm" è il trasfer che stava attorno ai 40 MB se non ricordo male (comunque più tardi riavvio e posto tutto esattamente);
- i filesystem sono entrambi ext4, partizioni primarie.

A dopo per l'"hdparm -i".

Sparo una cavolata: potrebbe essere un problema di kernel? Nel senso: i driver del kernel che sta usando per il suo hardware sono un po' buggati (o in versione sperimentale) e si manifesta come cpu-bound fuori norma.
Parlo da inesperto e probabilmente sto dicendo delle fesserie :doubt: .

Infine sì, i file che copiavo erano piuttosto grandi.

Edit: pare, ma devo fare verifiche più serie, che il problema sia limitato all'uso di KDE. Se verifico definitivamente questa cosa, ve la confermerò.

Re: copia file e cpu a palla!

Messaggioda shark1500 » mer giu 09, 2010 7:30

Ma per vedere che la cpu andava "a palla" a che tool hai fatto riferimento? Perche` se ti sei fidato del plasmoide di kde per la cpu allora ti ha detto una bugia.

In realta` non e` la cpu che andava a palla, ma il disco, e quindi il problema risiede in altri fattori (disco lento e scheduler non tanto buono)

Io credo che sia un limite fisico delle partizioni, per questo sconsiglio di partizionare il disco se non per l' installazione di un dual o multi boot.
Per copiare un file da una partizione all' altra é necessario far spostare la testina del disco migliaia di volte da una zona all' altra,probabilmente poi con il passaggio da una partizione all' altra, verranno memorizzati in un buffer e se questo buffer é sul disco allora gli accessi al disco raddoppiano rendendo il processo veramente inefficiente. Probabilmente la cosa avviene in modo meno dispendioso se la cosa avviene all' interno di una filesysem, il caso limite si ha con lo spostamento dei dati da una partizione all'altra, mentre per spostare i dati da una directory ad un' altra all' interno della filesystem é un operazione che avviene a livello di riscrittura di qualche settore.

Io ho un problema simile, ma che si manifesta quando copio grandi files da o verso un disco esterno, usando sia kde che cp.
Il filesystem del disco esterno è ext3, quindi niente fuse...

Sì, me n'ero accorto.
Allora ho fatto il confronto tra la Slack 13.0 (32 bit) e la Slack 13.1 (64 bit) con gkrellm e mentre nel primo caso la copia degli stessi grossi file non fa mai andare i due core oltre il 10%, nel secondo caso a volte superano anche il 30% e mi bloccano il sistema.
Ormai sono sicuro dalle prove fatte, che il problema sia solo di KDE, confermando i miei sospetti (ma non solo miei), che sia ben lontano dalla stabilità e usabilità del ramo 3.5.

Offtopic: Io ho risolto passando a xfce :D . Se anche xfce incomincerà a darmi incertezze passerò a icewm 8) .

Se il disco é usb trasferisce a solo 18-20 Mb/s cinque volte più lento di un 3.5'' SATA moderno che trasferisce sui 100Mb/s
