[LiveCodeServer / on-Rev] SqlLite - Insert…. very slow

i have here a script which
- creates a local sqlLite DB
- creates a Table with 13 fields
- insert 3000 records from a textfile
On my Mac this takes about 20 seconds. On an iPhone this take approx. 60 seconds plus the download time for the 3000 line textfile.
So i thought doing this on the server and let the iphone just download the gezipped sqlite file is much faster.
So i tried this with livecode server on the On-Rev system. It takes about 4 minutes to run the script.
I tried to do the sql inserts one by one and also in segments of 10,50,100. Nothing improves the processing time.
Is this a normal behaviour under livecode server? I thought this could be done in 2 or 3 seconds.
My code looks like this
put "produkte.sqlite" into tDatabasePath
put revOpenDatabase("sqlite", tDatabasePath, , , , ) into tDatabaseID
repeat for each line l in tList
--tList contains 3000 lines with 13 items each
put "NSERT INTO produkte VALUES ('value-01','value-02','value-03','value-04','value-05','value-06','value-07','value-08','value-09','value-10','value-11','value-12','value-13');" into tSQL
replace "value-01" with item 1 of l in tSQL
replace "value-02" with item 2 of l in tSQL
replace "value-03" with item 3 of l in tSQL
replace "value-13" with item 13 of l in tSQL
revExecuteSQL tDatabaseID, tSQL
I tried this with livecode server 3.5.0 (original on-rev) and livecode server 5.0.2.
Any ideas anyone?
