 Posted: Wed May 25, 2005 8:42 pm Post subject: [HW] Scrittura lenta su FAT [RISOLTO] |
 |
|
Ciao,
Non so come mai, ma qualche ricompilazione del kernel fa continuo ad avere qualche problema di lentezza nella scrittura su filesystem fat. Al momento non ho una partizione fat su HD, ma lavoro con hd esterni usb, lettori mp3 e chiavi usb in fat.
Se formatto la chiavetta in ext3, la velocita' su USB 2.0 e' di alcuni MB/s. Ma se la utilizzo in fat, passa a 64 KB/s !!!
Posto alcune info:
Kernel Linux 2.6.11-gentoo-r9

Qualcuno ha idee sul da farsi?
Grazie

notizia flash: Fat è lento patchato all'inverosimile e buggato uno schifo
definirlo un fs è fargli un complimento.
Se vuoi vedere delle prestazioni ( e avere un minino di sicurezza)
passa ad un fs journaled sempre se la situazione te lo permette

io pero a volte mi chieddo se il probblema non sia linux....
non e che linux riconoscendo VFAT come un suo nemico fa' di tutto per far in modo che uno non possa accederci...almeno non senza probblemi??? |

Stiamo lottando per rendere linux compatibile con qualsiasi architettura, formato di file e filesystem.. e ti pare che Linus si mette a fare ste boiate  |

Grazie, ho risolto disabilitando | Code: | | Device Drivers ---> Block devices ---> < > Low Performance USB Block driver |
escludendolo anche come modulo.
Scusate, non volevo creare un doppione ed intasare il forum , e che credevo dipendesse da FAT32, visto che non avevo notato prestazioni basse con ext3. 
Grazie ancora a tutti per l'aiuto
