23-08-12, 07:48soloilmeglioPer gmaps puó essere dovuto alla frequenza minima dei 100 mhz... setta 200-1400.... io sto cosí.... la 100 mhz non serve a niente non capisco perchè notecore e goku l'abbiano previstaQuote:

23-08-12, 08:03squall13ho settato a 200Mhz min e 1400Mhz max, ondemand e cfq (dici che cfq va bene o devo mettere deadline o noop?? per essere sincero non sò cosa siano)Quote:

I/O SCHEDULERS
Q. "What purposes does an i/o scheduler serve?"
A.
[*]Minimize hard disk seek latency.[*]Prioritize I/O requests from processes.[*]Allocate disk bandwidth for running processes.[*]Guarantee that certain requests will be served before a deadline.
So in the simplest of simplest form: Kernel controls the disk access using I/O Scheduler.
Q. "What goals every I/O scheduler tries to balance?"
A. [*]Fairness (let every process have its share of the access to disk)[*]Performance (try to serve requests close to current disk head position first, because seeking there is fastest)[*]Real-time (guarantee that a request is serviced in a given time)
Q. "Description, advantages, disadvantages of each I/O Scheduler?"
A.
1) Noop
Inserts all the incoming I/O requests to a First In First Out queue and implements request merging. Best used with storage devices that does not depend on mechanical movement to access data (yes, like our flash drives). Advantage here is that flash drives does not require reordering of multiple I/O requests unlike in normal hard drives.
Advantages:
[*]Serves I/O requests with least number of cpu cycles. (Battery friendly?)[*]Best for flash drives since there is no seeking penalty.[*]Good throughput on db systems.
Disadvantages:
[*]Reduction in number of cpu cycles used is proportional to drop in performance.
2) Deadline
Goal is to minimize I/O latency or starvation of a request. The same is achieved by round robin policy to be fair among multiple I/O requests. Five queues are aggressively used to reorder incoming requests.
Advantages:
[*]Nearly a real time scheduler.[*]Excels in reducing latency of any given single I/O.[*]Best scheduler for database access and queries.[*]Bandwidth requirement of a process - what percentage of CPU it needs, is easily calculated.[*]Like noop, a good scheduler for solid state/flash drives.
Disadvantages:
[*]When system is overloaded, set of processes that may miss deadline is largely unpredictable.
3) CFQ
Completely Fair Queuing scheduler maintains a scalable per-process I/O queue and attempts to distribute the available I/O bandwidth equally among all I/O requests. Each per-process queue contains synchronous requests from processes. Time slice allocated for each queue depends on the priority of the 'parent' process. V2 of CFQ has some fixes which solves process' i/o starvation and some small backward seeks in the hope of improving responsiveness.
Advantages:
[*]Considered to deliver a balanced i/o performance. [*]Easiest to tune.[*]Excels on multiprocessor systems.[*]Best database system performance after deadline.

Scusa ho dimenticato gli svantaggi del cfq
Disadvantages:
[*]Some users report media scanning takes longest to complete using CFQ. This could be because of the property that since the bandwidth is equally distributed to all i/o operations during boot-up, media scanning is not given any special priority.[*]Jitter (worst-case-delay) exhibited can sometimes be high, because of the number of tasks competing for the disk.

Secondo mè il notecore 14 va bene ma ha il solito problema. ...se navighi consuma come un pazzo. .... Ma oggi sono in un posto che non prende bene non è affidabile il mio consumo anche xè da questa mattina dalle 07.30 ad ora 11.40 sono al 87% ricordo sempre con notecore 14. ......
