I agree this should not be considered a long term solution, its simply shinning a flash light on a very poor performing area of the dark code. :) but its a very notable gain in performance without the cache.<br><br><div class="gmail_quote">

<p>Yay for mistakes that end in gains!!! of course if anyone
asks i planned this ;P anyway i thought people would like to see my ini
changes.. this is what lead to the discovery:<br>
<br>
[OpenSim.ini]<br>
; The following is the configuration section for the new
style grid servers<br>
; If you don't know what this is, don't enable it. It will
eat your data,<br>
; format your hard drive and make all meat in your fridge
spoil.<br>
; You have been warned.<br>
; Some of this is starting to work!<br>
[Modules]<br>
; Choose one <br>
;AssetServices = "LocalAssetServicesConnector"<br>
AssetServices = "RemoteAssetServicesConnector"<br>
;AssetServices = "HGAssetBroker"<br>
<br>
; If you don't want asset caching in the regions, comment
this<br>
AssetCaching = "CoreAssetCache"
;<<<---*** SEE ERROR HERE ***---->>><br>
<br>
; Choose one<br>
;UserServices = "LocalUserServicesConnector"<br>
UserServices = "RemoteUserServicesConnector"<br>
<br>
<br>
[AssetService]<br>
; Parameters for local assets, formerly known as
"standalone"<br>
LocalServiceModule =
"OpenSim.Services.AssetService.dll:AssetService"<br>
StorageProvider = "OpenSim.Data.SQLite.dll"<br>
;StorageProvider = "OpenSim.Data.MySQL.dll"<br>
;ConnectionString = "Data
Source=localhost;Database=opensim;User ID=opensim;Password=opensim;"<br>
DefaultAssetLoader =
"OpenSim.Framework.AssetLoader.Filesystem.dll"<br>
AssetLoaderArgs = "assets/AssetSets.xml"<br>
<br>
; Parameters for remote assets, formerly known as
"grid"<br>
AssetServerURI = "<a href="http://assets.osgrid.org:8003/" target="_blank">http://assets.osgrid.org:8003/</a>"<br>
<br>
; Paremeters for the Hypergrid connector<br>
<br>
;; Parameters for the HG Broker<br>
; Use this one if you have a standalone grid<br>
;LocalGridAssetService =
"OpenSim.Services.AssetService.dll:AssetService"<br>
; Use this one if this sim is connected to a grid-wide asset
server<br>
;LocalGridAssetService =
"OpenSim.Services.Connectors.dll:AssetServiceConnector"<br>
;HypergridAssetService =
"OpenSim.Services.AssetService.dll:HGAssetService"<br>
<br>
[AssetCache]<br>
; Number of buckets for assets<br>
CacheBuckets = 32768<br>
<br>
[UserService]<br>
;LocalServiceModule =
"OpenSim.Services.UserService.dll:UserService"<br>
<br>
[/OpenSim.ini]<br>
<br>
Please test this out and see if you see gains too and let us know.<br>
