Timeshift: RAMdisk or dedicated Harddisk (1 Viewer)

[polarie]

salute -

just got a question.

i read that post here:
TV-Server/UserGuides/Ramdisk - MediaPortal Wiki Documentation

now my problem is, that the time i could buffer a stream is a little low, couse i am runnning XPpro (max 3.5gig of useable RAM)

BUT a ramdisk solution is faster an better i think (switching-channel-time etc.)

i hav an "old" 160 Gbyte HDD (ATA133 master - no slave @ IDE = full bandwidth usable for that HDD) with no job anymore in my server.

will that be not as much performant as a ramdisk?
(i know that RAM is MUCH MUCH MUCH faster than a harddisk)
or will there be not much difference couse of using that HD only for timeshift makes it fast in that job....

Hi,

I have dedicated 1GB to a ramdisk for timeshifting on my system (XP Pro, 4GB RAM) and it can keep about half an hour for timeshifting. Should be enough for "normal" breaks, I think.

If you need more, you'll either need a larger Ramdisk or put the timeshifting on that unused HD.

The difference in switching speed in my case wasn't that big. Channel-switching takes it's time anyway on digital tv-solutions. On my system (DVB-S, no HD-channels and no encrypted channels) it takes about 2-3 sec. to switch. Ok for me. I did the ramdisk timeshifting thing just because "it's possible" and I like to test different solutions

Maybe this german thread could be interesting for you, if you want to try the ramdisk solution:

I doubt you will experience speed improvements when using
a seperate hd for timeshifting.
I didn't even notice a noticeable improvement during testing with a ram disk.

Using ramdisk as timeshifting buffer location is not going to improve the performance. HD is not the bottleneck when it comes to TVE3 performance (zapping for example). The issues are in DVB cards (tuning takes few hundred times the amount as accessing the correct TS buffer location on HD) and MP code.

ah now i c ...

ok .. so i will use that HDD not the RAM .. couse HD-Space is much more available ...
so the pause-time and back-hopping would hold longer than one cigarette

thx for the answers and hinds
