138848 Website speedup

Hi there, We have a website running which needs page-load optimization. The dedicated server configuration: MB: Supermicro PDSMi+ Intel Core Duo, 1066 MHz on 2.13GHz/Dual-Core, 2 MB cache Supermicro SNK-P0011 passive heatsink RAM: 1GB (2x512 MB) PC4200/533Mhz DDR2 Sdram 2x320 GB Segate SATAII 16 MB cache HDDs Slim CD-rom & FDD 1U Chassis, 300W PS - Supermicro SC813MT-300 Operation System : Debian GNU/Linux MySQL Version : mysql Ver 14.7 Distrib 4.1.11, for pc-linux-gnu (i386) PHP Version : 4.4.0 We already enabled MySQL cache with: | Qcache_free_blocks | 3 | | Qcache_free_memory | 16311032 | | Qcache_hits | 148 | | Qcache_inserts | 163 | | Qcache_lowmem_prunes | 0 | | Qcache_not_cached | 6 | | Qcache_queries_in_cache | 121 | | Qcache_total_blocks | 278 | | Questions | 2499 | We asked for enable-fastcgi, but host said that they could not do this because this would require the whole php to be recompiled for my server. , my guess it would be possible. they already did disable KeepAlive connection, which may reduce the available connections of the Apache web server, when pages with many images are loaded. Also I have increased some MySQL setting. The new values are double the old ones. key_buffer = 21M max_allowed_packet = 2M thread_stack = 256K So i really like help on this one!
