Utilizzo CPU 100%

beppegrillo · 12-01-2005, 17:15

Spesso mi capita, mentre compilo, installo o faccio qualche procedura simile che la cpu salga al 100% e blocchi completamente le altre operazioni, tale che ad esempio se compilo non posso nemmeno vedere un sito web.
Succede anche a voi o è solo un problema mio?
OS. Slackware - cpu amd barton.

E' corretta la prima (utilizzo processore al 100%), ma non la seconda (a meno che non compili con -j xxx). Penserei a problemi di velocità di accesso al disco.

Già hai ragione, non sò perchè ma non avevo pensato alla velocità di accesso al disco.

Quello è normale. I 33 MHz non sono la velocità del disco, ma la velocità del bus PCI. Più è alto, più linux imposta misure "conservative", quindi lascialo così com'è.

Strano però che ottenga questi risultati:
hdparm -Tt /dev/hda2

/dev/hda2:
Timing cached reads: 2012 MB in 2.00 seconds = 1005.67 MB/sec
Timing buffered disk reads: 22 MB in 3.01 seconds = 7.31 MB/sec

Mi pare siano in linea con un disco ata 133 no?

Veramente penoso. Sei in linea con un Commodore 64.

Penso che l'hd sia impostato su PIO, come faccio a saperlo e come lo imposto su UDMA? Mi pare si utilizzi sempre hdparm giusto?

hdparm -i. A volte mente.

Tre possibilità:
1) è un disco sata e vale anche 2)
2) hai una combinazione chipset+disco in blacklist. Il kernel disabilita il dma per evitare corruzione dei dati (in questo caso forse dmesg dovrebbe dare qualche informazione).
3) hai ricompilato il kernel per caso?

Il disco è un maxtor 120gb ATA133, il kernel 2.6.9 è stato ricompilato.
Ecco cosa ottendo da dmesg:

Ok già si ragiona.

Puoi allegare il tuo file di configurazione del kernel così vediamo come mai non attivava l'udma in automatico?

Succede anche a voi o è solo un problema mio? OS. Slackware - cpu amd barton. __________________ Ciao ~ZeRO sTrEsS~

ilsensine Senior Member Iscritto dal: Apr 2000 Città: Roma Messaggi: 15625	Tre possibilità: 1) è un disco sata e vale anche 2) 2) hai una combinazione chipset+disco in blacklist. Il kernel disabilita il dma per evitare corruzione dei dati (in questo caso forse dmesg dovrebbe dare qualche informazione). 3) hai ricompilato il kernel per caso? __________________ 0: or %edi, %ecx; adc %eax, (%edx); popf; je 0b-22; pop %ebx; fadds 0x56(%ecx); lds 0x56(%ebx), %esp; mov %al, %al andeqs pc, r1, #147456; blpl 0xff8dd280; ldrgtb r4, [r6, #-472]; addgt r5, r8, r3, ror #12

ilsensine Senior Member Iscritto dal: Apr 2000 Città: Roma Messaggi: 15625	E' corretta la prima (utilizzo processore al 100%), ma non la seconda (a meno che non compili con -j xxx). Penserei a problemi di velocità di accesso al disco. __________________ 0: or %edi, %ecx; adc %eax, (%edx); popf; je 0b-22; pop %ebx; fadds 0x56(%ecx); lds 0x56(%ebx), %esp; mov %al, %al andeqs pc, r1, #147456; blpl 0xff8dd280; ldrgtb r4, [r6, #-472]; addgt r5, r8, r3, ror #12
