Are you going to need high io for a demanding application or are you just looking to waste your time looking for something that's not realistic and needed?
I'm with digitalocean and have seen their io changing drastically from derplet to derplet.
Here was shit, delete pls
and what might be a high speed today, might not be tomorrow, or what might give a good result on one test, another might not.
If you really need high I/O, get a dedi with SSD. If you only want some stupid benchmark with I/O you can't abuse, get a RamNode.
Ramnode pure SSD has to be the highest, beaware of hosts posting dd results with ploop.
Like the DD test would have any meaningful value.
I need fast io vps , i am not wasting time
What do you need it for? If you are actually going to use the "fast IO" for prolonged periods, please consider getting a dedi instead.
i am working on website with sqlite database and need high io for fast reading and writing
And how large is your database?
Ugh. SQLite isn't really designed for large/busy databases...
You are, if you need the fastest IO you need to be able to quantify what the means. Thrashing IO can be abuse in the same way hogging your 1 shared core can be. So if you really do know what you requirements are then back it up with some real requirements.
Not very large 50 MB
I know but it is good for me to use the sqlite with this script
50mb I don't think it requires very high io to be efficient.
you must try it , if you want to do multiple operations (read/write) on it you need very high io for the sqlite database or there will be delay with response
This. It will all be cached in RAM anyway. Any decent VPS should do, though nowadays i'd always buy a SSD VPS if i don't need large space.
@tarek4web, yeah and sequential DD test will definitely tell you the true result :-). Good luck.
Oh my ...
somehow I agree with you
/facepalm
another dd porn
Familiar with the term - You are a fud!
1st thing 50MB database != 50MB write or read on every access
2nd thing, dd is single threaded process, disk speed can be much higher than your results are showing.
3rd thing, why dont you cache whole db in RAM ?
alot of operations need fast io speed
example 10 operations per second need the database file to be read and written 10 times per second 50mb io speed can do only one operation per second
I will try to explain you this on really simple way. Once when your DB engine (SQLite) open your db myimaginaryDB(50MB).db and requests 20kb of information, you will do exactly 20kb read + headers. Same for write, if you are committing 20kb to database you are doing 20kb write plus headers which includes all relevant thing to that write.
Big writes / reads can happen on sorting or deleting or idk what mass read you will do, however those are really rare for "classic webpages".
I hope that i have explained you core of your problem and i hope that you understand now what specs are you actually looking for.
@tarek4web You need dedi at least with a dual e5 24 thread, 512gb ram and 16 ssd in raid 10 to run that kind of database. Simple vps won't work.
A TL:DR of what @drserver said, that's simply not how databases work, not even close.
@drserver just launch that diskporn already!
You have just saved my domain name. It was pending for deletion because i forgot to renew it. (facepalm)
Yay, thanks for the beers! Oh wait, I don't drink alcohol...
I can offer you a vps on my new quickpacket ssd node please check here latest offer: http://www.lowendtalk.com/discussion/61378/offers-from-cubedata#latest
